A Pioneering Medical Doctor Who was a Vet

From Wikipedia:

Jane Hinton (1919–2003) was a pioneer in the study of bacterial antibiotic resistance and one of the first two African-American women to gain the degree of Doctor of Veterinary Medicine (1949).

Prior to her veterinary medicine studies at the University of Pennsylvania, she had been a laboratory technician at Harvard, co-developing the Mueller-Hinton agar, a culture medium that is now commonly used to test bacterial susceptibility to antibiotics. She later practiced as a small animal veterinarian in Massachusetts, and then as a federal government inspector.

Hinton was the daughter of William Augustus Hinton, a microbiologist and the first African-American professor at Harvard University.
