oct 10, 1878 - Robert Koch

Description:

Robert Koch (Germany: 1878), who discovered how to stain and grow bacteria in a Petri dish (named after his assistant Julius Petri). He was thus able to find which bacteria caused which diseases:
Anthrax (1876)
septicaemia (1878)
TB (1882)
cholera (1883).

He developed a specific way of dyeing bacteria so that they were visible to him under a microscope and developed a method of photographing what was under a microscope.
