Alice Evans, American Microbiologist

Alice Catherine Evans (January 29, 1881 - September 5, 1975) was an American microbiologist. She became a researcher at the US Department of Agriculture. There she investigated bacteriology in milk and cheese. She later demonstrated that Bacillus abortus caused the disease Brucellosis in both cattle and humans. She was met with skepticism, because she was a woman and did not have a Ph.D. Her findings led to the pasteurization of milk in 1930. As a result, the incidence of brucellosis in the US was significantly reduced. Evans also contributed to the field of infectious illness, studying epidemic meningitis and influenza.
