Lafayette Benedict Mendel

Died 9 Dec 1935 at age 63 (born 5 Feb 1872).American biochemist whose discoveries concerning the value of vitamins and proteins helped establish modern concepts of nutrition. Collaborating with Thomas Osborne, together they published more than 100 papers on various aspects of nutrition (1909-28). In 1913, they showed that rats developed xerophthalmia on diets in which lard supplied the fat. The condition was cured by substitution of butterfat. Thus, they discovered butterfat contained a growth- promoting factor necessary for development, soon known as fat-soluble vitamin A, (co-discovered simultaneously by Elmer McCollum). Mendel also contributed to discovery of B complex vitamins (1915) and linked the nutritive value of proteins to their amino acids.
