Best Answer - Chosen by Asker:
It depends on the definition of "discover"!.

In the mid 1800s, most people believed that one could get cholera from breathing foul air!. But John Snow, a physician in London, thought that cholera was transmitted through water!. He wrote an assay with that theory in 1849!.

But in 1854, during a large cholera outbreak in London, he actually proved this theory!. He made a map of all the houses in London with cholera cases, and he discovered that most cases were clustered around a water pump on Broad Street!. He then had the handle removed, so that people had to go to other water pumps!. According to this famous story, the cholera cases then dropped dramatically (in reality, the cholera outbreak was already fading out)!.

This is probably the first time that someone took a map to look for disease patterns, and so John Snow is believed to be the first epidemiologist!.

So although John Snow speculated that water was the source of cholera in his 1849 essay, he proved his theory in 1854!. So I think that 1854 is the best answer!.Www@QuestionHome@Com
