He gained scholarship after the completion of his preliminary studies to Yale University, New York. In 1891, he graduated in classics, economics, and humanities alongside biology and chemistry with a Degree in honors. He then performed his graduate work at the Sheffield scientific school where he studied physiological Chemistry under Russell Henry Chittenden. In 1893, he finished his Ph.D. course with the ‘Study of Seed Storage Protein Edestin Extracted from Hemp seed’ as his thesis topic.

Career

After his Ph.D., Lafayette Mendel became the assistant in physiological chemistry at Sheffield School. He then studied the aspects of physiological chemistry in Germany for a short while. In 1896, he returned from Germany and became the assistant professor at the Yale University. In 1903, he became a full-time professor. He was among the top-ranked Jewish professors in the United States of America.

In 1913, he together with Osborne found that butterfat constituted Vitamin A whereas water-soluble Vitamin B was abundant in milk and both were complimentary for healthy living. They later found out that a person lacking vitamin A had a risk of suffering from Xerophthalmia.

Lafayette Mendel then profounded the importance of tryptophan and lysine in a balanced, healthy diet. They also found out that the amount of amino acids in a protein determines its nutritive value. They wrote more than 100 articles. In 1916, he wrote his article ‘Changes in the Food Supply and Their Relation to Nutrition’. In 1923, his article ‘Nutrition, the Chemistry of Life’ was published.  In 1921, he served as the Sterling Professor of Physiological Chemistry.

Awards And Achievements

Lafayette Mendel was the first President of the American Institute of Nutrition. In 1913, he joined the National Academy of Sciences. In 1921, he served as the Yale university’s Sterling professor. In 1927, due to his outstanding Chemistry contributions, he received a gold medal from the American Institute of Chemists. In 1935, he won the Conné Medal of the Chemist’s Club of New York.
