Imagine having to dodge the contents of emptied bedpans or step over rotting corpses on the way to work. That was a reality of city life before technology, public policy, and public values began to focus on the effects of poor sanitation. In this immersive three-part series, sophisticated computer animation and in-depth scholarship bring history’s struggles with urban filth vividly to life. The case studies: medieval London, 18th-century Paris, and New York City during its most intense phase of European immigration. A BBC/Discovery Coproduction. 3-part series, 50 minutes each.
