Marguerite Davis (September 16, 1887 – September 19, 1967) was an American biochemist, co-discoverer of vitamins A and B with Elmer Verner McCollum in 1913.[1]

In his 1964 autobiography, McCollum attributes his success in nutrition research to two people: Davis and Stephen Babcock. He also says that Davis was physically handicapped by severe burns that she received at age ten while playing at a bonfire when her clothing caught fire.[2]

She earned a bachelor of science degree in home economics[3] in 1910 at the University of California, Berkeley.[4] She then returned to the University of Wisconsin where she started but did not complete a master's degree. She moved to New Jersey, to work for the Squibb Pharmaceutical Company, later returning to the University of Wisconsin to teach and do research for a number of years.[5]

In 1913, Davis and McCollum identified what they termed fat-soluble A and water-soluble B, renamed later vitamins A and B,[6] after long research on rats.[7]

Davis founded the nutrition laboratory at the University of Wisconsin. She later helped Rutgers University in New Jersey form a nutrition lab as part of its School of Pharmacy. She pursued history and gardening after her retirement in 1940.[5]

Davis died in Racine three days after her eightieth birthday on September 19, 1967.[5]
