- Elmer McCollum
Elmer McCollum (
March 3 ,1879 –November 15 ,1967 ) was an American biochemist.McCollum was born on a farm near
Fort Scott, Kansas , where he spent his first seventeen years. He worked at odd jobs to finish high school and college, graduating from theUniversity of Kansas in 1903 and earning his doctorate atYale University in 1906. As a faculty member in agricultural chemistry at the University of Wisconsin, he established the nation's first colony of white lab rats to use for his nutrition experiments.He isolated the growth-promoting factors now called
Vitamin A andVitamin B , distinguishing fat-soluble and water-soluble forms, and later showed that B is not a single compound, but a complex. McCollum and biochemist-in-training Marguerite Davis gave the "factors" letter names, because their structures had not yet been determined to give them proper chemical names.McCollum opposed
Casimir Funk 's 1912 name vitamins because he thought they were no more "vital" than other nutrients and because they are not true amines. The name was changed to its current spelling in 1920.In 1917
Johns Hopkins University recruited McCollum as professor ofbiochemistry , although he almost didn't get the job. At 6 feet and just 127 pounds, the nutritionist looked "frail" to the faculty members who interviewed him.He published 150 papers at Johns Hopkins, reporting research work on tooth decay, vitamins D and E, and the role of trace minerals in nutrition, including aluminum, calcium, cobalt, fluorine, phosphorus, potassium, manganese, sodium, strontium and zinc. McCollum worked with
Herbert Hoover 's U.S. Food Administration to alleviate starvation in Europe in the aftermath ofWorld War I . His classic textbook The Newer Knowledge of Nutrition went through multiple editions.After his 1946 retirement, he wrote "The History of Nutrition" and an autobiography. McCollum received many awards, honors and medals in his life and died in 1967 rich in rewards. His home in Baltimore is a National Historic Landmark, and the American Society for Nutrition sponsors a McCollum lecture and gives the E.V. McCollum Award each year to "a clinical investigator who is perceived currently as a major creative force, actively generating new concepts in nutrition."
McCollum was a great believer in nutrition through food. To his dying day, McCollum regarded drugstore vitamin pills and supplements as snake-oil quackery. He died on
November 15 ,1967 at the age of 88. Shortly before his death, he remarked: "I have had an exceptionally pleasant life and am thankful."References
