The New-York Historical Society has a great-sounding new exhibit up:  Plague in Gotham!  Cholera in 19th C New York.  Cholera was an urban scourge in the 19th century, and public health physicians and bacteriologists studying cholera epidemics led to some really interesting discoveries and innovations (cf John Snow; also the London sewers).  Charles Rosenberg’s brilliant little book, The Cholera Years, which discusses cholera epidemics mostly in New York, in 1832, ’49 and ’66, is a classic in the history of medicine, and an artifact-based telling of these epidemic stories sounds great.  The NYHS has an exhibit blog up, which provides additional material on cholera, the epidemics and the exhibition, including a neat map of important locations in their story in 1832.  Go see it for me; I won’t be in NYC this year. The exhibit runs through June 28.
