Alice C. Evans: breaking barriers.

Despite severe and persistent criticism of her research, Alice Evans persevered in her pioneering work on the bacterial contamination of milk, identifying the organism that caused undulant fever and demonstrating that drinking unpasteurized cow's milk could transmit the disease, undulant fever, to humans. The opprobrium that Alice Evans endured was unrelenting, even after her election as the first President of the Society of American Bacteriologists, (now the American Society for Microbiology), but she remained undeterred, a true heroine of American microbiology and a magnificent public health worker.
