WEBVTT 00:01.560 --> 00:05.050 Prof: This morning we'll take up one of the themes-- 00:05.050 --> 00:08.910 that is to say, we've described how the course 00:08.914 --> 00:13.874 is about specific diseases, but it's also about a number of 00:13.868 --> 00:17.298 overarching themes, and one of those is the 00:17.297 --> 00:21.167 development of various public health strategies. 00:21.170 --> 00:25.020 So far, as you'll remember, we've dealt with three public 00:25.016 --> 00:26.386 health strategies. 00:26.390 --> 00:32.250 One was the system of plague measures: sanitary cordons, 00:32.253 --> 00:37.483 lazarettos, quarantine, and all the rest of it. 00:37.480 --> 00:42.180 We've dealt with vaccination as a public health strategy, 00:42.175 --> 00:45.525 with regard to smallpox in particular. 00:45.530 --> 00:50.480 And we've talked about a third policy, if we want to dignify it 00:50.484 --> 00:54.964 in that way, and this was the strategy of concealment. 00:54.960 --> 00:59.460 This morning I want to talk about a fourth approach to 00:59.460 --> 01:02.860 public health, and this was what's called 01:02.856 --> 01:05.826 commonly the sanitary movement. 01:05.828 --> 01:11.878 This was pioneered in Britain in the 1830s and '40s, 01:11.879 --> 01:17.259 and it was then exported to the continent in North America, 01:17.260 --> 01:21.110 assuming particular forms in France and Italy, 01:21.110 --> 01:26.420 with the actual rebuilding of cities in accord with sanitary 01:26.420 --> 01:27.590 principles. 01:27.590 --> 01:33.090 Now, the sanitary movement was the first to define itself as a 01:33.093 --> 01:37.333 public health movement, and it had two essential 01:37.334 --> 01:39.684 meanings for its term. 01:39.680 --> 01:45.130 The first was the prevention of infectious epidemic diseases, 01:45.126 --> 01:48.936 and the second was the removal of filth. 01:48.940 --> 01:52.680 So, it's based, in a sense, on the relationship 01:52.680 --> 01:54.550 of filth and disease. 01:54.550 --> 01:59.160 Indeed, many people talk about the filth theory of disease as 01:59.163 --> 02:02.703 lying at the basis of the sanitary movement. 02:02.700 --> 02:07.350 Its focus, therefore, was on the towns and cities 02:07.347 --> 02:12.577 that had sprung up with urbanization and the industrial 02:12.576 --> 02:14.026 revolution. 02:14.030 --> 02:18.680 Epidemic diseases disproportionately claimed their 02:18.677 --> 02:23.697 victims in the cities, and correspondingly the legacy 02:23.697 --> 02:28.287 of lasting effects was especially pronounced in urban 02:28.287 --> 02:31.517 areas, and the sanitary movement is 02:31.519 --> 02:34.119 one of those lasting legacies. 02:34.120 --> 02:39.980 Now, there is a theory that we may as well look at, 02:39.979 --> 02:43.499 just for a second, developed by the British 02:43.504 --> 02:49.034 physician and demographer, Thomas McKeown--and it's often 02:49.030 --> 02:53.690 called his thesis-- where he was dealing with the 02:53.686 --> 02:58.966 demographic fact of what he called a mortality revolution; 02:58.970 --> 03:02.700 a demographic transition in which cities, 03:02.699 --> 03:06.339 for the first time, become places that are 03:06.340 --> 03:11.670 dependent for their expansion not only on inward migration to 03:11.668 --> 03:15.408 the towns, but on the fact that the 03:15.407 --> 03:21.327 longevity and the birthrate come to exceed the death rate; 03:21.330 --> 03:25.340 which was something new, a real demographic revolution. 03:25.340 --> 03:27.930 And why was this achieved? 03:27.930 --> 03:34.640 Many people have thought and postulated that it was due to 03:34.635 --> 03:39.925 medical science, to conscious policy and those 03:39.930 --> 03:42.990 sorts of explanations. 03:42.990 --> 03:46.500 McKeown instead stresses two factors. 03:46.500 --> 03:50.220 He sees this as largely unplanned and due to improved 03:50.216 --> 03:54.576 nutrition, but also--and that's the point this morning--to the 03:54.575 --> 03:56.215 role of sanitation. 03:56.220 --> 03:59.310 In other words, the population explosion, 03:59.310 --> 04:04.330 the demographic revolution, is something that he postulates 04:04.328 --> 04:07.578 was due to, not to medical science, 04:07.575 --> 04:10.935 but rather to the sanitary movement, 04:10.939 --> 04:13.559 and also to nutrition. 04:13.560 --> 04:17.820 Well, what was the background to the sanitary movement? 04:17.819 --> 04:23.109 We've seen and mentioned that there really was a tremendous 04:23.112 --> 04:27.772 challenge to health in this period of the industrial 04:27.766 --> 04:30.956 revolution in European history. 04:30.959 --> 04:35.819 There were tremendous changes afoot in British society. 04:35.819 --> 04:40.629 There was the rise of a modern commercial agriculture, 04:40.625 --> 04:45.425 and with it enclosure, the driving of peasants off the 04:45.432 --> 04:46.252 land. 04:46.250 --> 04:50.130 We know about the major demographic growth that was 04:50.125 --> 04:53.655 underway by this period, supported by the new 04:53.663 --> 04:57.783 agriculture and the fading of the threat of famine and the 04:57.776 --> 05:00.226 fading of the threat of plague. 05:00.230 --> 05:03.350 There was the rise of manufacture, 05:03.350 --> 05:07.320 and then the factory system, especially the textile 05:07.317 --> 05:10.047 industry, and the associated and 05:10.045 --> 05:14.155 unregulated horrors of things such as long hours, 05:14.160 --> 05:17.630 low wages, child labor. 05:17.629 --> 05:20.109 You know, too, that across Europe, 05:20.110 --> 05:24.620 urban populations doubled in the first half of the nineteenth 05:24.622 --> 05:27.852 century, and in so doing overwhelmed the 05:27.845 --> 05:30.375 infrastructure of available jobs, 05:30.379 --> 05:33.599 the housing stock, sanitary arrangements, 05:33.600 --> 05:36.320 and all the rest, so that we see the rise of 05:36.319 --> 05:39.559 tenement slums, sweatshops. 05:39.560 --> 05:45.460 There was a mass movement of population from countryside to 05:45.459 --> 05:50.849 town, and with that went psychological adjustments. 05:50.850 --> 05:55.810 There was a breakdown of older notions of social relations 05:55.809 --> 06:00.069 based on paternalism, of the customary notion of a 06:00.072 --> 06:03.902 moral economy based on moral obligation. 06:03.899 --> 06:08.439 And we see instead the rise of the principles of impersonal 06:08.440 --> 06:11.210 relations, of a free-market economy, 06:11.209 --> 06:14.439 and laissez-faire, epitomized in the new 06:14.437 --> 06:18.737 discipline of political economy, with such figures, 06:18.744 --> 06:23.564 of course, as Adam Smith, Ricardo, Jeremy Bentham, 06:23.562 --> 06:25.432 Thomas Malthus. 06:25.430 --> 06:29.580 The result, along with those transformations, 06:29.577 --> 06:32.967 was a rise of new social tensions. 06:32.970 --> 06:37.240 We've talked about the nineteenth century as the 06:37.240 --> 06:39.150 rebellious century. 06:39.149 --> 06:42.789 Now, in Britain, there were no social and 06:42.786 --> 06:48.996 political revolutions, nothing comparable to 1789 in 06:48.997 --> 06:52.277 France, or to what happened on the 06:52.276 --> 06:57.276 continent in 1830, and in 1848 and '49. 06:57.279 --> 07:01.349 But contemporaries weren't certain at all that this was 07:01.353 --> 07:04.753 going to be a lasting fortune for Britain, 07:04.750 --> 07:10.300 and indeed Britain did have a number of signs of severe social 07:10.300 --> 07:11.940 tension as well. 07:11.939 --> 07:14.779 There were large-scale riots. 07:14.778 --> 07:20.138 One could mention the Chartist Movement, and in the countryside 07:20.136 --> 07:23.416 the movement known as Captain Swing. 07:23.420 --> 07:26.950 So, urban and industrial centers, also in Britain, 07:26.949 --> 07:31.449 were perceived as dangerous, politically, 07:31.449 --> 07:35.689 for fear of the so-called dangerous classes who rioted, 07:35.690 --> 07:40.320 perhaps committed crime, threatened revolution, 07:40.319 --> 07:43.679 and were dangerous medically, as well; 07:43.680 --> 07:51.460 that is, they were infected with cholera and other diseases. 07:51.459 --> 07:56.349 And it was cholera in particular that was a real prod 07:56.348 --> 08:01.988 to action, this new and most feared disease of the nineteenth 08:01.990 --> 08:03.120 century. 08:03.120 --> 08:06.660 It's not by chance, then, that the sanitary 08:06.658 --> 08:11.038 movement begins in the 1830s and '40s in Britain, 08:11.040 --> 08:16.650 after, that is to say, the first pandemic and the 08:16.648 --> 08:19.918 second of Asiatic cholera. 08:19.920 --> 08:25.800 And it lasts intermittently down through the First World 08:25.798 --> 08:26.438 War. 08:26.439 --> 08:30.439 And this really was a vast movement. 08:30.439 --> 08:34.369 It was nothing less than the retrofitting of the urban 08:34.374 --> 08:38.884 centers of the nation, with the specific goal of 08:38.884 --> 08:43.754 removing filth, because filth was held to be 08:43.746 --> 08:46.146 the cause of disease. 08:46.149 --> 08:50.959 So, we're talking about one of the great public works projects 08:50.961 --> 08:54.431 of modern history: the establishment of sewer 08:54.433 --> 08:58.423 systems, a whole infrastructure of water 08:58.416 --> 09:01.126 mains, of waste removal, 09:01.129 --> 09:05.469 street cleansing, improved and less crowded 09:05.470 --> 09:09.790 housing, the creation of parks and public spaces. 09:09.788 --> 09:16.708 We can see that Victorian Britain truly was preoccupied 09:16.712 --> 09:22.742 with that combination of excrement and water. 09:22.740 --> 09:26.930 All of this, of course, presupposed as well 09:26.927 --> 09:30.317 the emergence of a modern state. 09:30.320 --> 09:34.590 It was state power that alone provided the wealth and 09:34.586 --> 09:39.426 organizational structures that were needed to carry out this 09:39.427 --> 09:41.147 enormous project. 09:41.149 --> 09:46.049 And in turn we can see the causal chain working in both 09:46.053 --> 09:51.053 ways, because the sanitary movement was a very important 09:51.048 --> 09:54.498 factor in reinforcing state power. 09:54.500 --> 10:00.250 Its implementation meant that the state now invaded areas of 10:00.248 --> 10:05.508 life formerly regarded as private, and appropriated for 10:05.509 --> 10:08.529 itself enormous new powers. 10:08.528 --> 10:12.598 And the reformers were supported by Protestant and 10:12.596 --> 10:16.246 especially evangelical Christian churches. 10:16.250 --> 10:18.880 Well, who were the leaders of this movement? 10:18.879 --> 10:23.329 I think we should turn first of all to this man, 10:23.331 --> 10:25.321 Sir Edwin Chadwick. 10:25.320 --> 10:29.050 This is Edwin, Sir Edwin, in his younger days. 10:29.048 --> 10:33.358 This may be a slightly more familiar picture of him, 10:33.355 --> 10:35.545 I guess maybe at my age. 10:35.548 --> 10:40.478 In any case, Sir Edwin wrote a major work 10:40.477 --> 10:44.057 collaboratively-- he produced it, 10:44.056 --> 10:48.996 let us say--which was called "The Report on the Sanitary 10:49.003 --> 10:53.623 Condition of the Labouring Population of Great Britain of 10:53.620 --> 10:54.940 1842." 10:54.940 --> 10:58.420 Now, Chadwick wasn't a physician at all, 10:58.418 --> 11:03.318 and this is part of the background perhaps to the thesis 11:03.322 --> 11:05.912 I was mentioning earlier. 11:05.908 --> 11:11.278 He was instead a lawyer by training from Manchester. 11:11.278 --> 11:16.948 And he was already well known, in particular for his reform of 11:16.947 --> 11:22.767 welfare provisions in Britain; that is, he was responsible in 11:22.773 --> 11:25.373 large part, for the passage, 11:25.370 --> 11:30.570 from the old poor law, which had provided relief as 11:30.566 --> 11:35.636 the birthright of every citizen in distress; 11:35.639 --> 11:42.089 that is, the right to some form of assistance or aid in time of 11:42.086 --> 11:43.226 distress. 11:43.230 --> 11:48.530 Chadwick's idea was to economize, to minimize the cost 11:48.529 --> 11:54.829 of payments, to discourage the poor from applying for relief. 11:54.830 --> 11:58.970 He wanted to make the experience of receiving relief 11:58.966 --> 12:03.426 more painful than the experience of distress itself, 12:03.428 --> 12:07.668 a principle that was dubbed "the principle of least 12:07.668 --> 12:09.208 eligibility." 12:09.210 --> 12:11.960 The workhouse, in other words, 12:11.960 --> 12:16.320 was to be a place of punishment, of pain and of 12:16.322 --> 12:17.652 suffering. 12:17.649 --> 12:20.809 So, work should be, in the workhouse, 12:20.813 --> 12:26.003 more unpleasant than any to be found in the labor market. 12:26.000 --> 12:30.740 And the diet should be intentionally made to be 12:30.743 --> 12:36.313 loathsome, more so than what could be found by the poor 12:36.312 --> 12:37.552 outside. 12:37.548 --> 12:42.238 The poor law bureaucracy was also invoked, 12:42.240 --> 12:47.470 and was an essential foundation of the information on which 12:47.471 --> 12:52.341 Chadwick relied for the sanitary report of the laboring 12:52.342 --> 12:55.232 population of Great Britain. 12:55.230 --> 12:59.460 This was the man who was the same in both faces, 12:59.460 --> 13:04.230 with the new poor law and with the sanitary report. 13:04.230 --> 13:11.000 The sanitary reform was also a stark assertion of state power 13:11.000 --> 13:14.500 as a means of social control. 13:14.500 --> 13:19.710 The intention was to discipline and civilize the working classes 13:19.706 --> 13:22.926 in the interests of social stability. 13:22.928 --> 13:27.718 Following in the wake of the report was the establishment of 13:27.720 --> 13:31.130 a Public Health Act of 1848 in Britain, 13:31.129 --> 13:36.579 and a general Board of Health, and such champions of sanitary 13:36.580 --> 13:42.090 reform as John Simon, Thomas Southwood Smith and Neil 13:42.090 --> 13:42.950 Arnott. 13:42.950 --> 13:49.080 Now, let's talk for a minute about this man's ideology and 13:49.081 --> 13:50.911 his intentions. 13:50.909 --> 13:55.099 This was a class-based movement. 13:55.100 --> 13:59.150 It was top-down and centralizing. 13:59.149 --> 14:02.259 In Chadwick's mind, the poor were largely 14:02.264 --> 14:04.994 responsible for their own plight. 14:04.990 --> 14:09.110 They weren't innocent, and they certainly weren't 14:09.114 --> 14:10.064 harmless. 14:10.058 --> 14:15.958 His mission was to cleanse and civilize the dangerous classes. 14:15.960 --> 14:21.750 As I said, he wasn't a physician, and his reforms were 14:21.745 --> 14:26.545 not based on any new medical discoveries, 14:26.548 --> 14:31.668 on scientific experimentation or observation to determine what 14:31.671 --> 14:36.371 measures were most effective by determining the causes of 14:36.371 --> 14:37.381 disease. 14:37.379 --> 14:41.769 His reform measures, enormous as they were, 14:41.774 --> 14:48.264 were based more on what was the commonsense of the period and a 14:48.263 --> 14:50.673 priori assumptions. 14:50.668 --> 14:52.878 Public health, in this way, 14:52.878 --> 14:57.548 was separate from the development of medical science. 14:57.548 --> 15:02.578 His view--and this was widely accepted--was that medicine was 15:02.576 --> 15:06.846 about private persons, not so much public policy. 15:06.850 --> 15:11.950 And his idea was to use public policy to cleanse the urban 15:11.951 --> 15:17.141 environment, but not to deal with other social and economic 15:17.143 --> 15:19.653 determinants of disease. 15:19.649 --> 15:21.419 We'll talk about that in a moment. 15:21.418 --> 15:25.548 We need to think about not only about what Chadwick wanted to 15:25.547 --> 15:27.687 do, but we also need to think about 15:27.692 --> 15:31.142 what he decided not to do, what wasn't important to him. 15:31.139 --> 15:34.629 And so we should see this as progress, yes, 15:34.629 --> 15:39.449 but progress that came at a cost, and we want to know about 15:39.447 --> 15:40.857 that as well. 15:40.860 --> 15:45.100 Now, an influence on Chadwick's thinking was "The Essay on 15:45.100 --> 15:47.700 Population" of Thomas Malthus, 15:47.700 --> 15:52.010 who believed that there was a law that in every society 15:52.010 --> 15:56.880 population pressure sooner or later pressed against the limits 15:56.881 --> 15:58.401 of subsistence. 15:58.399 --> 16:03.439 So, real improvement for the poor was likely to be illusory, 16:03.437 --> 16:07.277 short-term, and perhaps counter-productive. 16:07.278 --> 16:10.208 In the long run, really significant improvement 16:10.212 --> 16:12.702 couldn't occur, according to Malthus. 16:12.700 --> 16:15.630 It might even be self-defeating, 16:15.629 --> 16:19.219 leading to disease, starvation and war, 16:19.221 --> 16:24.421 those great positive checks on population increase. 16:24.418 --> 16:29.388 That idea of the limited nature of possible improvement was in 16:29.392 --> 16:35.172 Chadwick's mind; the poor will always be with us. 16:35.168 --> 16:39.368 There was also, as I said, the filth theory of 16:39.366 --> 16:40.296 disease. 16:40.299 --> 16:41.789 We know it. 16:41.788 --> 16:47.308 We've talked about miasma and its long history in European 16:47.311 --> 16:48.281 thought. 16:48.279 --> 16:53.659 Well, filth now was associated very closely with smell. 16:53.658 --> 16:57.518 And if you are to read the report at some point, 16:57.517 --> 17:02.357 you would notice that smells constitute an important part of 17:02.359 --> 17:03.589 the report. 17:03.590 --> 17:08.460 The report is filled with descriptions of stench. 17:08.460 --> 17:13.090 The authorities consulted by Chadwick frequently used phrases 17:13.089 --> 17:17.129 such as, "I was assailed by a most 17:17.127 --> 17:22.027 disagreeable smell, and it was clear to me that the 17:22.025 --> 17:25.975 air was full of most injurious malaria." 17:25.980 --> 17:30.320 By malaria, that's another word that occurs throughout the 17:30.315 --> 17:30.995 report. 17:31.000 --> 17:34.900 And we should note that before malaria came to mean a specific 17:34.904 --> 17:37.404 disease, it meant "bad air," 17:37.403 --> 17:39.633 from the Italian mal' aria, 17:39.630 --> 17:40.530 bad air. 17:40.529 --> 17:44.239 And, so, this report, in Britain in the 1840s, 17:44.242 --> 17:49.032 is filled with descriptions of what they called malaria. 17:49.029 --> 17:53.939 Let me give you an example from the town in the West Country of 17:53.944 --> 17:54.584 Truro. 17:54.578 --> 17:59.458 Reporting to Chadwick, the reporting official said, 17:59.464 --> 18:01.614 "Passing into St. 18:01.614 --> 18:05.914 Mary's Parish, the proportion of sickness and 18:05.913 --> 18:10.313 deaths is as great as any part of Truro. 18:10.308 --> 18:14.788 But there's no mystery at all in the causation. 18:14.788 --> 18:19.278 Ill-constructed houses with decomposing refuse, 18:19.278 --> 18:22.518 clothes upon their doors and windows, 18:22.519 --> 18:27.089 open drains, bring the oozings of pigsties 18:27.088 --> 18:32.548 and filth to stagnate at the foot of the walls. 18:32.548 --> 18:36.788 Such are a few of the sources of disease, which even the 18:36.788 --> 18:40.488 breezes from the hills cannot dissipate." 18:40.490 --> 18:45.530 Everywhere the reports discovered disease, 18:45.529 --> 18:51.169 and they correlated the disease with such findings as poisonous 18:51.171 --> 18:54.361 vapor, morbific effluvia, 18:54.356 --> 19:01.236 filth, obnoxious effluvia, poisonous exhalations, 19:01.240 --> 19:04.150 miasma and malaria. 19:04.150 --> 19:08.670 The moral of the texts of those conditions also preoccupied 19:08.665 --> 19:11.465 those who took part in the report. 19:11.470 --> 19:14.420 Vice, alcohol, intemperance, 19:14.415 --> 19:18.555 and then more poverty, and still worse, 19:18.563 --> 19:20.203 more filth. 19:20.200 --> 19:25.530 Poverty was partly the result of depravity and improvidence, 19:25.528 --> 19:30.858 and those in turn reinforced more poverty and more filth. 19:30.858 --> 19:35.448 Well, there was a political aim behind the sanitary reform, 19:35.450 --> 19:40.570 and I think we might call this a transformation that Chadwick 19:40.565 --> 19:45.505 was aiming at in the demographic composition of the British 19:45.510 --> 19:46.790 population. 19:46.788 --> 19:50.118 In Chadwick's mind, trade unions, 19:50.115 --> 19:53.645 which he abhorred, demonstrations, 19:53.650 --> 19:58.120 strikes, the Chartist Movement, and all the rest, 19:58.118 --> 20:02.268 were called by Chadwick "wild and dangerous 20:02.267 --> 20:04.117 assemblages." 20:04.118 --> 20:09.168 But he noted that they were mainly led by the young. 20:09.170 --> 20:15.100 Older, experienced workmen, with family responsibilities, 20:15.101 --> 20:21.241 he found to be moderate and temperate, and not to take part 20:21.243 --> 20:24.743 in strikes and social unrest. 20:24.740 --> 20:29.430 Therefore a high early death rate, 20:29.430 --> 20:33.980 and poor sanitary conditions, were actually politically 20:33.984 --> 20:37.144 destabilizing, at least in his mind, 20:37.144 --> 20:41.174 because they led to the early death of workmen, 20:41.170 --> 20:44.650 and hence to an overrepresentation of the 20:44.646 --> 20:49.556 dangerous young, and an under-representation of 20:49.557 --> 20:52.377 moderating older workmen. 20:52.380 --> 20:56.410 If we want to understand and explain this view, 20:56.412 --> 21:01.762 perhaps we could invoke an anachronism, to make an analogy. 21:01.759 --> 21:06.359 And we could use the analogy of a nuclear reactor, 21:06.364 --> 21:11.914 and compare social unrest to a meltdown of the reactor core, 21:11.907 --> 21:15.007 with disastrous consequences. 21:15.009 --> 21:19.599 Well, in terms of the reactor, to prevent such events reactors 21:19.596 --> 21:21.546 make use, as you know, 21:21.545 --> 21:26.855 of boron control rods that are inserted to control the rate of 21:26.856 --> 21:30.076 fission of uranium and plutonium, 21:30.079 --> 21:33.769 and to limit chain reactions. 21:33.769 --> 21:37.039 In this way, what Chadwick wanted to do, 21:37.038 --> 21:42.418 by analogy, was to use older people like control rods that 21:42.423 --> 21:48.283 would have the calming effect of preventing social meltdown and 21:48.280 --> 21:50.360 social revolution. 21:50.358 --> 21:54.768 But to do that you had to do something about infectious 21:54.772 --> 21:59.192 diseases, to achieve this demographic transformation of 21:59.186 --> 22:00.736 the population. 22:00.740 --> 22:06.000 So, if infectious disease was destabilizing for the state and 22:06.002 --> 22:09.862 political order, a population subject to 22:09.862 --> 22:15.582 infectious disease moreover is unlikely to be educated and to 22:15.583 --> 22:20.163 be open to the moral influence of the clergy. 22:20.160 --> 22:25.480 And the absence of cleansing in towns, Chadwick felt, 22:25.481 --> 22:29.991 would lead also to demoralization and further 22:29.986 --> 22:31.416 depravity. 22:31.420 --> 22:37.180 Now, in all of this thinking, let's remember too at what was 22:37.175 --> 22:37.855 lost. 22:37.858 --> 22:43.328 A striking feature of Chadwick's view was the 22:43.327 --> 22:46.557 narrowness of its focus. 22:46.558 --> 22:50.438 The cause of ill health in Victorian Britain-- 22:50.440 --> 22:52.370 I think we should say not the cause-- 22:52.368 --> 22:55.358 the causes were undoubtedly multiple, 22:55.358 --> 22:57.748 and one could think about low wages, 22:57.750 --> 23:01.540 unregulated factories, inadequate diet, 23:01.538 --> 23:04.408 poor clothing, lack of education, 23:04.414 --> 23:07.654 working conditions in sweatshops, 23:07.650 --> 23:10.240 mines and factories, child labor, 23:10.239 --> 23:12.019 overcrowded housing. 23:12.019 --> 23:16.449 These I would call social and economic determinants of 23:16.452 --> 23:17.292 disease. 23:17.288 --> 23:21.228 And there were voices, particularly on the continent, 23:21.229 --> 23:25.019 for an alternative public health that would address 23:25.018 --> 23:27.668 precisely such broad interests. 23:27.670 --> 23:31.510 There was an older tradition of what was called a "medical 23:31.512 --> 23:35.212 police" on the continent, and a current of thought of 23:35.212 --> 23:38.032 what was called "social medicine", 23:38.029 --> 23:42.899 whose most prominent figure was this man, 23:42.900 --> 23:48.690 Rudolph Virchow, a Prussian physician who lived 23:48.686 --> 23:52.826 from 1821 to 1902, and was one of the great 23:52.833 --> 23:55.343 figures of nineteenth century medicine; 23:55.338 --> 23:58.398 a physician, anthropologist, 23:58.396 --> 24:02.356 biologist and radical politician. 24:02.358 --> 24:06.538 Now, his view was that disease was not simply a biological 24:06.538 --> 24:09.618 event, but a socially driven phenomenon. 24:09.618 --> 24:13.188 And his meaning of the term "social medicine" 24:13.194 --> 24:16.574 was that physicians should treat not just individual 24:16.571 --> 24:21.821 patients but entire societies, and that they should pay great 24:21.815 --> 24:25.515 attention to matters of the economy, 24:25.519 --> 24:29.509 to diet, wages, housing, child labor, 24:29.509 --> 24:32.149 working conditions. 24:32.150 --> 24:37.480 Virchow was, in a sense, the anti-Chadwick. 24:37.480 --> 24:45.070 Chadwick's intention instead was to focus on the narrow issue 24:45.067 --> 24:50.657 of filth and water, and his attention was confined 24:50.664 --> 24:56.114 to the working classes and the filth in which they lived. 24:56.108 --> 25:01.798 At stake was the issue of how broad should a public health 25:01.800 --> 25:03.200 movement be? 25:03.200 --> 25:08.290 And perhaps one could say that one of the sad features of the 25:08.289 --> 25:13.469 period was the triumph of the narrowest gauge vision of public 25:13.465 --> 25:14.395 health. 25:14.400 --> 25:18.150 The solution, in Chadwick's hands--and this 25:18.152 --> 25:23.242 was a major event in public health, there's no doubt about 25:23.243 --> 25:23.873 it. 25:23.868 --> 25:28.168 I'm trying to say--not that this was unfortunate--it was 25:28.170 --> 25:30.360 only unfortunately narrow. 25:30.358 --> 25:36.118 Chadwick's solution involved technological measures, 25:36.115 --> 25:40.395 all good in themselves: drains, sewers, 25:40.404 --> 25:42.214 water pipes. 25:42.210 --> 25:46.780 But they didn't include social, economic and educational 25:46.780 --> 25:47.530 reform. 25:47.529 --> 25:50.649 And the reforms all came from above, 25:50.650 --> 25:54.270 and reinforced a centralizing state, 25:54.269 --> 25:58.679 rather than finding ways to empower ordinary people to 25:58.679 --> 26:02.339 participate in defending their own health. 26:02.338 --> 26:05.818 Let me give you an example of a simple technological 26:05.815 --> 26:06.765 improvement. 26:06.769 --> 26:11.009 It might be hard to recognize when you first look at it but-- 26:11.009 --> 26:15.899 and I'm talking about some very humble movements that have 26:15.895 --> 26:19.835 enormous political and medical consequences. 26:19.838 --> 26:22.878 What we're looking at is a sewer main, 26:22.880 --> 26:28.870 and these were established under the soil of cities in this 26:28.866 --> 26:31.736 period, and one of the technological 26:31.743 --> 26:34.843 inventions was to make the sewers egg shaped, 26:34.838 --> 26:39.778 so that you would maximize the flow and they would be 26:39.779 --> 26:44.909 self-cleaning and they would drain most efficiently. 26:44.910 --> 26:50.560 So, technological innovations of that sort were part of it. 26:50.558 --> 26:56.248 Now, the victory of Chadwick's vision of public health wasn't 26:56.252 --> 27:00.432 simply automatic, and so it was worth to keep 27:00.426 --> 27:02.796 alternatives in mind. 27:02.798 --> 27:07.528 His side was the winning side in a debate of the early 27:07.529 --> 27:10.739 nineteenth century, and a wider view, 27:10.742 --> 27:13.692 like that of Virchow, was present, 27:13.689 --> 27:16.009 but lost the debate. 27:16.009 --> 27:22.029 Let's be clear in summation. 27:22.028 --> 27:26.828 I'd argue that Chadwick's vision of public health was 27:26.830 --> 27:31.110 highly successful, that it was a crucial part of 27:31.113 --> 27:35.643 the mortality revolution of nineteenth century Europe, 27:35.640 --> 27:39.180 but that at the same time something was lost, 27:39.180 --> 27:42.870 a broad vision of the causes of disease, 27:42.868 --> 27:46.978 and those causes weren't addressed. 27:46.980 --> 27:51.310 Although what Chadwick achieved was a major and positive 27:51.313 --> 27:54.783 advance, it perhaps fell short of what 27:54.777 --> 27:58.477 might have been, and it demonstrates the 27:58.480 --> 28:03.120 practical and positive impact of miasmatic theory. 28:03.118 --> 28:06.248 And public health, a theory--and this is perhaps 28:06.249 --> 28:08.779 something we ought to bear in mind-- 28:08.778 --> 28:14.278 that a theory that is by now rejected-- 28:14.278 --> 28:18.938 that is miasmatism, the filth theory of disease-- 28:18.940 --> 28:25.260 did operate in such a way as to promote major and positive 28:25.256 --> 28:27.136 health results. 28:27.140 --> 28:31.780 And one of the causes of this movement was the epidemic 28:31.782 --> 28:36.172 disease that we dealt with the last couple of times, 28:36.167 --> 28:38.917 and that is Asiatic cholera. 28:38.920 --> 28:44.090 We might note there was a sidelight that may be of 28:44.093 --> 28:48.443 interest as well; that this sanitary movement, 28:48.438 --> 28:53.978 the literal sanitary movement, was accompanied in some places 28:53.979 --> 28:59.239 by what we might call a figurative sanitary movement, 28:59.240 --> 29:04.770 and that is moral sanitation. 29:04.769 --> 29:09.059 And one of those was particularly notable in France 29:09.061 --> 29:13.441 where there was a great fear of another disease, 29:13.440 --> 29:16.690 that we'll be talking about slightly later in the course, 29:16.690 --> 29:19.000 and that is syphilis. 29:19.000 --> 29:24.390 Remember, the early nineteenth century, we're dealing with the 29:24.391 --> 29:28.281 period in the wake of the Napoleonic wars. 29:28.278 --> 29:33.048 And with those wars, as always happens--or 29:33.047 --> 29:39.787 happened--there was a major upsurge in socially transmitted 29:39.791 --> 29:44.561 diseases, and in particular syphilis. 29:44.558 --> 29:49.268 And so this sanitary movement was accompanied by the movement 29:49.273 --> 29:54.303 for moral sanitation through the registration and surveillance of 29:54.301 --> 29:55.561 prostitutes. 29:55.558 --> 30:01.548 And in France those responsible for moral sanitation actually 30:01.551 --> 30:06.201 made the link explicit; that is to say that they 30:06.200 --> 30:10.590 compared brothels with sewers, and said that they, 30:10.590 --> 30:14.180 the brothels, should become the target of 30:14.175 --> 30:15.605 sanitation. 30:15.608 --> 30:20.968 So this was a form of moral sanitation that was an offshoot 30:20.973 --> 30:26.343 of the literal sanitary movement that is our main theme. 30:26.338 --> 30:33.438 The sanitary worldview led also on the continent to further 30:33.438 --> 30:38.088 offshoots, and that--I want to talk now 30:38.087 --> 30:43.767 about a continental form of the sanitary movement, 30:43.769 --> 30:48.009 the rebuilding of cities in their entirety. 30:48.009 --> 30:52.579 This was actually much more comprehensive and systematic. 30:52.579 --> 30:55.849 It means urban planning. 30:55.848 --> 31:00.358 It's more comprehensive than what happened in Britain, 31:00.364 --> 31:05.304 which was the retrofitting of cities with sewers and drains 31:05.304 --> 31:07.694 and sanitary provisions. 31:07.690 --> 31:11.830 It entailed the actual leveling of whole cities, 31:11.829 --> 31:15.789 or neighborhoods within them, to start afresh, 31:15.794 --> 31:19.674 in accordance with a comprehensive plan. 31:19.670 --> 31:22.030 There were a number of prototypes. 31:22.028 --> 31:27.328 In France, Paris, Lyon and Marseilles. 31:27.329 --> 31:29.819 In Belgium, Brussels. 31:29.818 --> 31:32.908 In Naples--that is in Italy, there was Naples, 31:32.911 --> 31:34.971 as you know, but also Florence, 31:34.971 --> 31:37.171 La Spezia, and other places. 31:37.170 --> 31:43.000 But let's begin in Paris, because that established the 31:43.000 --> 31:44.100 pattern. 31:44.098 --> 31:50.528 Here again we see the influence of epidemic cholera, 31:50.532 --> 31:57.222 which ravaged Paris in the 1830s and again in 1849. 31:57.220 --> 32:02.190 And this caused an enormous psychological shock, 32:02.192 --> 32:08.652 the idea that civilization was no sure-fire protection against 32:08.647 --> 32:12.137 sudden and agonizing disease. 32:12.140 --> 32:16.560 There was an unbearable contradiction that a city, 32:16.558 --> 32:20.538 that is Paris, that prided itself at being at 32:20.539 --> 32:24.429 the heart of European intellectual life, 32:24.430 --> 32:29.080 at being the leading city in the arts and culture, 32:29.078 --> 32:31.738 a world center, as you now know, 32:31.739 --> 32:35.779 of scientific medicine, could nevertheless be 32:35.780 --> 32:40.870 devastated by a disease that was associated with poverty, 32:40.868 --> 32:46.788 with filth, and with the colonial world. 32:46.788 --> 32:51.748 Well, after the revolutions of 1848 to '49, 32:51.750 --> 32:57.900 we have a reactionary and authoritarian regime established 32:57.903 --> 33:03.453 by Louis Napoleon Bonaparte, or Napoleon III, 33:03.452 --> 33:08.552 that soon became the Second Empire, 33:08.549 --> 33:13.749 that lasted from 1851 'til 1870. 33:13.750 --> 33:16.000 There's Napoleon III. 33:16.000 --> 33:20.420 He undertook a major movement to rebuild Paris. 33:20.420 --> 33:24.270 And I want to argue that this had enormous sanitary 33:24.268 --> 33:26.828 consequences, intentionally so, 33:26.827 --> 33:30.807 and that the experience of epidemic cholera was very 33:30.809 --> 33:34.089 important in the establishment of that. 33:34.088 --> 33:39.038 But I don't want to say that the rebuilding of Paris was 33:39.042 --> 33:44.182 solely designed as a health measure, and solely to prevent 33:44.178 --> 33:46.518 the return of cholera. 33:46.519 --> 33:49.109 There were other gains as well. 33:49.108 --> 33:54.028 Napoleon III wanted imperial splendor. 33:54.029 --> 33:59.389 He wanted a city that would be worthy of the role of France in 33:59.385 --> 34:04.295 the world, that would be a showcase for his new political 34:04.304 --> 34:05.274 regime. 34:05.269 --> 34:09.389 He too was thinking about social control. 34:09.389 --> 34:13.939 So, there was a political aim; that was, to destroy the 34:13.938 --> 34:20.098 working class slums that had been the sites of rebellion. 34:20.099 --> 34:25.619 The idea was to use urban renewal to remove workers from 34:25.615 --> 34:30.125 the center of the city to distant suburbs, 34:30.130 --> 34:35.920 and in the center to construct wide boulevards that could not 34:35.920 --> 34:40.970 be defended by barricades, and that the troops could use 34:40.972 --> 34:43.772 to move quickly across the cities, 34:43.768 --> 34:48.268 and cannonballs could fire down the boulevards to demolish 34:48.273 --> 34:49.303 barricades. 34:49.300 --> 34:52.840 In other words, Paris was to be made 34:52.840 --> 34:57.900 revolution-proof, or at least that was the goal. 34:57.900 --> 35:01.530 It was also a project of public works; 35:01.530 --> 35:05.430 that is, it was a means of enormous patronage. 35:05.429 --> 35:09.949 It would provide employment and would defuse social tensions as 35:09.949 --> 35:10.459 well. 35:10.460 --> 35:16.550 So, Paris, under Napoleon III, became a vast public works 35:16.550 --> 35:21.120 project, enormous shovel-ready projects. 35:21.119 --> 35:26.139 The workers of Paris then would be employed and therefore 35:26.144 --> 35:27.854 largely pacified. 35:27.849 --> 35:31.959 It was thought that this would also have an economic role. 35:31.960 --> 35:34.960 The new boulevards, the wide spaces, 35:34.958 --> 35:40.008 would facilitate the movement of goods and assist free trade 35:40.012 --> 35:41.472 and commerce. 35:41.469 --> 35:45.989 And then there was the public health objective: 35:45.987 --> 35:50.107 to improve health, to prevent the return of 35:50.114 --> 35:52.574 infectious epidemics. 35:52.570 --> 35:58.450 The task was entrusted to this man, Georges Haussmann, 35:58.445 --> 36:01.435 the Prefect of the Seine. 36:01.440 --> 36:05.420 And often what was accomplished is referred to as the 36:05.420 --> 36:08.560 "Haussmannization" of Paris, 36:08.559 --> 36:12.629 with the so-called great works, or grands travaux, 36:12.630 --> 36:18.280 that were undertaken from 1852 until 1870. 36:18.280 --> 36:22.590 Now, this project was authoritarian. 36:22.590 --> 36:25.940 The rights of individuals were disregarded. 36:25.940 --> 36:30.380 The population was not consulted about being moved, 36:30.378 --> 36:34.728 and it was an operation of colossal complexity. 36:34.730 --> 36:40.290 All of the affairs of one of the greatest cities in France, 36:40.289 --> 36:45.719 the great city in France, were gathered into a single 36:45.715 --> 36:48.425 pair of hands: finance, 36:48.429 --> 36:52.349 administration, transport, sanitation, 36:52.349 --> 36:55.009 engineering, architecture, 36:55.014 --> 36:58.894 evictions, expropriation of land by 36:58.893 --> 37:02.273 eminent domain, slum clearance, 37:02.268 --> 37:06.338 gas fixtures and lighting, sewers. 37:06.340 --> 37:11.390 All of this was an enormous assertion, then, 37:11.391 --> 37:13.391 of state power. 37:13.389 --> 37:17.739 The means were broad intersecting boulevards. 37:17.739 --> 37:21.389 Let me show you the sorts of plans-- 37:21.389 --> 37:25.619 were to have the great boulevards of Paris, 37:25.619 --> 37:32.279 that you can see today--such as the Rue de Rivoli, 37:32.280 --> 37:35.130 Boulevard de Strasbourg, S�bastopol, 37:35.130 --> 37:36.690 the Boulevard Saint-Michel. 37:36.690 --> 37:40.750 The average size width of a street in Paris was to be 37:40.746 --> 37:45.266 doubled, and underneath the streets there were to be sewers 37:45.268 --> 37:46.438 and drains. 37:46.440 --> 37:50.410 There was to be water supply, and there were to be broad 37:50.413 --> 37:54.463 parks and public spaces, such as the Bois de Boulogne. 37:54.460 --> 37:59.450 The aesthetics were the aesthetics of the straight line. 37:59.449 --> 38:00.889 We can see that there. 38:00.889 --> 38:03.569 We can see it also here. 38:03.570 --> 38:06.510 And you can see the intersection of these broad 38:06.514 --> 38:09.994 boulevards, and you can see how these were 38:09.994 --> 38:13.534 multi-purpose and would allow not only-- 38:13.530 --> 38:17.360 part of the idea was the miasmatic one, 38:17.360 --> 38:22.330 that they would allow air and light to sweep through the city 38:22.327 --> 38:28.857 and remove the noxious smells, and purify and cleanse the city. 38:28.860 --> 38:34.910 And you can see as well that they would be good for commerce 38:34.914 --> 38:37.484 and for social control. 38:37.480 --> 38:43.680 So, Paris, after Haussmann, was clearly much healthier as a 38:43.682 --> 38:48.282 city than before, and cholera did not return 38:48.282 --> 38:51.922 thereafter to the city center. 38:51.920 --> 38:57.620 But there is an irony here, that cholera did return, 38:57.617 --> 39:00.967 less vehemently than before. 39:00.969 --> 39:05.729 But in the 1890s it did return, but not to the center of the 39:05.733 --> 39:06.303 city. 39:06.300 --> 39:10.170 In other words, part of the sanitary problem of 39:10.172 --> 39:14.732 Paris was not entirely solved, but was exported to the 39:14.731 --> 39:19.461 suburbs, and it was the suburbs that experienced the return of 39:19.456 --> 39:20.926 cholera in 1892. 39:20.929 --> 39:25.579 We have to see this as an enormous sanitary success, 39:25.579 --> 39:28.769 but one that we ought to qualify. 39:28.768 --> 39:33.888 Let me look at--let's look--this is a map--a picture 39:33.889 --> 39:38.809 of the demolition, to convince you of what a major 39:38.809 --> 39:41.319 undertaking this was. 39:41.320 --> 39:48.460 And there's a view of the new open spaces, cleansed with light 39:48.461 --> 39:51.391 and air, and germ free. 39:51.389 --> 39:57.499 And also in Napoleon III's mind, it would be also--make 39:57.503 --> 40:01.243 revolution much more difficult. 40:01.239 --> 40:05.749 Well there was--the political success, as well as the 40:05.753 --> 40:11.053 sanitary--was a success but one that needs to be qualified. 40:11.050 --> 40:15.450 There was an enormous resentment among the working 40:15.454 --> 40:19.234 people of Paris at Haussmann's project, 40:19.230 --> 40:24.150 and there was an enormous history from that time down to 40:24.152 --> 40:28.182 nearly our own of hostility of the suburbs. 40:28.179 --> 40:30.749 Paris becomes, not by chance, 40:30.750 --> 40:35.710 surrounded by a red belt of concluding hostility to the 40:35.708 --> 40:39.418 regime, and this exploded in the spring 40:39.420 --> 40:44.470 of 1871 in the Paris Commune that brought down the regime and 40:44.472 --> 40:48.012 led to the establishment of a republic. 40:48.010 --> 40:52.180 So, there are also political qualifications. 40:52.179 --> 40:56.409 Well, I'll move then to another example very quickly, 40:56.409 --> 41:01.979 and one that is in the reading, and that is the Italian 41:01.983 --> 41:05.613 version, and in particular the 41:05.606 --> 41:11.946 risanamento of Naples, which was Italy's largest city. 41:11.949 --> 41:15.759 As you know, there was a massive epidemic in 41:15.764 --> 41:19.944 the city-- this is the plan of 41:19.942 --> 41:27.012 risanamento in Naples-- and as you know, 41:27.012 --> 41:32.102 it led to the idea-- and here is something that is 41:32.101 --> 41:35.601 actually unique; that is to say that we've 41:35.603 --> 41:40.863 talked about the retrofitting of British cities and also American 41:40.862 --> 41:41.522 ones. 41:41.518 --> 41:45.088 We've talked about the rebuilding of Paris. 41:45.090 --> 41:50.650 Those were associated with a variety of disease experiences, 41:50.648 --> 41:55.548 and they had purposes other than a single disease. 41:55.550 --> 42:01.770 One can't see the retrofitting of British cities as due solely 42:01.768 --> 42:06.968 to epidemic cholera, nor the rebuilding of Paris. 42:06.969 --> 42:11.549 Here in Naples we have something that's unusual and 42:11.548 --> 42:16.298 probably unique, which is the actual rebuilding 42:16.304 --> 42:22.544 of a major European city for the specific purpose of preventing 42:22.536 --> 42:25.046 the return of cholera. 42:25.050 --> 42:30.570 And the way that the plan was developed reflected the specific 42:30.574 --> 42:36.014 medical understanding of the time of the cause of cholera. 42:36.010 --> 42:42.920 And we see here too a form of the filth theory of disease. 42:42.920 --> 42:46.740 The rebuilding of Naples was for this single purpose, 42:46.739 --> 42:52.849 and the medical theory behind the rebuilding project was 42:52.847 --> 42:58.957 specifically the miasmatic theory of this physician from 42:58.956 --> 43:02.096 Bavaria, Munich in particular, 43:02.101 --> 43:07.821 who is Max von Pettenkofer, who had an enormous influence 43:07.818 --> 43:09.908 on public health. 43:09.909 --> 43:15.709 And one aspect of his influence was that his theory lay at the 43:15.713 --> 43:19.143 basis of the rebuilding of Naples. 43:19.139 --> 43:22.819 He developed the most sophisticated of miasmatic 43:22.818 --> 43:26.888 theories in the nineteenth century and was aimed-- 43:26.889 --> 43:32.209 the aim then behind the rebuilding of Naples was to thin 43:32.208 --> 43:34.238 out the population. 43:34.239 --> 43:39.429 Overcrowding was a cause of disease, 43:39.429 --> 43:45.109 and poisonous vapors arising from underneath the city 43:45.106 --> 43:50.116 poisoned the air, people breathed in the poison 43:50.117 --> 43:56.617 and succumbed to cholera, in Max Pettenkofer's view. 43:56.619 --> 44:00.859 The purpose of risanamento then was 44:00.860 --> 44:05.930 first of all to raise the level of the streets; 44:05.929 --> 44:10.249 that is to say, the danger and the miasma was, 44:10.248 --> 44:15.718 if we like, fermenting beneath the streets of the city. 44:15.719 --> 44:21.279 So, you want to place a greater distance between the population 44:21.278 --> 44:26.748 living above and the poisonous effluvia arising from below. 44:26.750 --> 44:31.920 And, so, the aspiration was to raise the level of the streets 44:31.920 --> 44:35.110 to the second storey of the houses. 44:35.110 --> 44:37.670 And there would be, if you like, 44:37.666 --> 44:42.296 then a massive cushion, including the mortar of the 44:42.295 --> 44:46.995 streets themselves, between the population of the 44:46.996 --> 44:52.436 city and the danger lurking in the groundwater beneath the 44:52.436 --> 44:53.196 soil. 44:53.199 --> 44:57.259 In addition, the idea was that you would 44:57.259 --> 45:03.089 have Naples--there's a picture of the old city that's--in 45:03.088 --> 45:07.668 various aspects--that's been demolished; 45:07.670 --> 45:12.030 and here what I wanted to show was this, the great access at 45:12.028 --> 45:14.968 the center; and then there were various 45:14.969 --> 45:16.069 cross streets. 45:16.070 --> 45:20.980 The great boulevard at the center was in the direction of 45:20.981 --> 45:25.221 the prevailing wind, and it was called a bellows of 45:25.222 --> 45:29.892 fresh air that would allow the wind to rush through the city, 45:29.889 --> 45:36.179 drying up the effluvia and blowing away the stenches and 45:36.177 --> 45:41.547 allowing the sunlight to reach ground level, 45:41.550 --> 45:46.150 and then it would be crossed by a series of wide boulevards as 45:46.150 --> 45:46.680 well. 45:46.679 --> 45:50.199 And then under the--if this happened above ground, 45:50.199 --> 45:53.249 there would also be work going on beneath, 45:53.250 --> 45:59.270 and you would have a whole sewage mains being built under 45:59.266 --> 46:00.446 the city. 46:00.449 --> 46:04.189 So, risanamento, this enormous project, 46:04.186 --> 46:08.916 both above and below ground, was related-- it was a cousin 46:08.918 --> 46:12.238 of the sanitary movement in Britain. 46:12.239 --> 46:17.799 It was a first-cousin of the rebuilding of Paris and Lyon. 46:17.800 --> 46:21.880 But it was distinctive too, because it's the only example 46:21.876 --> 46:25.656 of a project conducted exclusively for the purpose of 46:25.659 --> 46:30.549 defeating a single disease, and that was cholera. 46:30.550 --> 46:32.750 Was it a success? 46:32.750 --> 46:35.610 Well, Naples was rebuilt. 46:35.610 --> 46:39.730 And there's no doubt that the health of the city thereafter 46:39.730 --> 46:42.430 was greater than it had been before. 46:42.429 --> 46:48.529 But unfortunately there too there were qualifications. 46:48.530 --> 46:53.510 The rebuilding was marred, marred perhaps partly by the 46:53.512 --> 46:57.482 flaws in its conception from the outset, 46:57.480 --> 47:03.940 but marred also by the fact of corruption and the misuse of the 47:03.936 --> 47:07.996 funds that were used to carry it out. 47:08.000 --> 47:13.800 And, so, we see thereafter that although Naples was rebuilt in 47:13.802 --> 47:18.952 the aftermath of 1884, that there was a return of 47:18.945 --> 47:25.535 cholera, a major epidemic again, in 1911. 47:25.539 --> 47:32.179 And there was even a small coda to that, which is another 47:32.182 --> 47:35.152 outbreak, even in 1973. 47:35.150 --> 47:37.790 So, the irony and conclusion. 47:37.789 --> 47:45.799 The sanitary movement in Britain, retrofitting of cities, 47:45.800 --> 47:48.840 the rebuilding of cities in France, 47:48.840 --> 47:53.930 the risanamento in Naples, did achieve major 47:53.931 --> 47:54.951 success. 47:54.949 --> 48:00.159 But it's worth remembering that they often weren't based on a 48:00.155 --> 48:03.275 medical theory that was to endure. 48:03.280 --> 48:07.370 And indeed in the case of Naples, it was a medical theory 48:07.367 --> 48:11.597 that very soon after the rebuilding was to be discarded. 48:11.599 --> 48:16.249 No sooner had Naples been rebuilt than the theories of 48:16.246 --> 48:21.066 Pettenkofer were overturned, with the coming of the germ 48:21.070 --> 48:23.000 theory of disease. 48:23.000 --> 48:26.900 So, when we're--one of the questions we ask, 48:26.896 --> 48:31.606 then, was the lasting impact of epidemic diseases. 48:31.610 --> 48:37.390 And I would argue that one of the senses of lasting impact is 48:37.393 --> 48:43.373 one that's embodied in bricks and mortar, in urban planning. 48:43.369 --> 48:49.729 And if you visit these cities, then you can see the lasting 48:49.730 --> 48:56.200 legacy of epidemic disease in the urban landscape itself. 48:56.199 --> 49:00.999
