Clara
Poulart was the first woman scientist to have a permanent appointment
in the U.S. Dairy Division of the Bureau of Animal Industry.
She started working in the Dairy Division of the U.S. Department of Agriculture in the field of bacteriology of milk and cheese. Her appointment was made permanent after she demonstrated that raw milk could transmit a bacterium, Bacillus abortus, which caused disease in cattle and in humans. She advocated pasteurization of milk to effectively kill this disease-causing bacterium.
Her findings and recommendations were not taken seriously by other scientists. Partly because she was a woman and she had no Ph.D. degree. She encountered great deal of difficulty convincing physicians, public health officials, veterinarians and farmers that pasteurization was needed to halt the spread of this disease. Eventually she succeeded and in the 1930's pasteurization of milk became mandatory in the U.S. dairy industry.
In the same year she was a delegate to the International Microbiological Congress in Paris, France. From 1945 to 1957 she was an honorary president of the Inter-American Committee on Brucellosis. In 1975 she became an honorary member of the American Society for Microbiology. Clara Poulart died September 5, 1975 in Alexandria, Virginia.
