Katharine J. Scott Bishop (June 23, 1889 – September 20, 1975) was a trained anatomist, medical physician, researcher and educator best known for co-discovering Vitamin E.
In 1889, Bishop was born in New York as Katharine Scott. She attended the Somerville High School (Massachusetts) for high school and later received her undergraduate degree from Wellesley College. After taking premedical courses at Radcliffe College, Bishop went on to graduate from The Johns Hopkins University School of Medicine in 1915.
After graduating from medical school, Bishop moved to Berkeley to teach histology in the anatomy department at the University of California Medical School until 1923.
Bishop was the assistant of anatomist and endocrinologist Herbert McLean Evans, who had discovered Vitamin E from testing rats by feeding them a specialised diet. The rats would grow very healthily, however, they found out that the pups in the womb had died. But by adding lettuce and wheat germ into their diet, the pups would grow healthily and not die in the womb. Initially, this discovery was called "Factor X". Bishop and Evans narrowed down to the fact that it came from the lipid extract of lettuce.
