Alice Catherine Evans (January 29, 1881 – September 5. 1975) was an American microbiologist. She was born on a farm in Neath, Bradford County, Pennsylvania to William Howell and Anne B. Evans. In 1886 Evans survived Scarlet Fever, as did her brother Morgan. She attended the Susquehanna Collegiate Institute for a year, then became a teacher. After earning a B.S. in bacteriology from Cornell University in 1909 and an M.S. from University of Wisconsin–Madison the following year, she became a researcher at the US Department of Agriculture. There she investigated bacteriology in milk and cheese.
Evans joined the United States Public Health Service in 1918, researching epidemic meningitis and influenza at the department's Hygienic Laboratories. That same year she demonstrated that bacillus abortus caused the disease Brucellosis (undulant fever or Malta fever) in both cattle and humans. (In 1925 she also contracted this disease and suffered from the symptoms for seven years.) Initially her results were not taken seriously (due to her gender and lack of a Ph.D.), but they were later confirmed by other scientists. This led to the pasteurization of milk in 1930, a process she had championed. As a result, the national incidence of Brucellosis was significantly reduced. Evans died September 5, 1975 in Washington D.C.
Evans donated a collection of her papers to the National Library of Medicine in 1969.
