From Pennsylvania farm girl to true heroine of American microbiology, Alice Catherine Evans (1881 – 1975) made one of the most medically important discoveries of the 20th-century. Unable to afford college, she started her career in 1901 as an elementary school teacher. But when Cornell University offered a free class on nature to rural teachers, Alice jumped at the chance and the course of her life (and history) subsequently changed.

While taking that nature class, Alice also took a basic course in the Agricultural College, which started her interest in bacteriology. Fast forward to winning a scholarship to Cornell, earning a Bachelor of Science degree in bacteriology (1909) and a Master of Science degree in the same field from the University of Wisconsin (1910), Alice landed a job in the Dairy Division at the U.S. Department of Agriculture Bureau of Animal Husbandry.

Her work involved investigating bacteriology in milk and cheese. When her appointment was made permanent in 1913, Alice became the first woman scientist to have a permanent appointment in that division of the USDA.
