History of medicine

Alice C. Evans was a scientist who made one of the most medically important discoveries of the 20th century. She identified a bacterial infection carried by cows that could cause undulating fevers in humans and published her findings in 1918. Dairy workers laughed at her warning that raw milk should be pasteurized to prevent people from developing disease. However, other scientists came to the same conclusion in the late 1920s and by the 1930s, the government enacted milk pasteurization laws.
