Lafayette Mendel

Lafayette Benedict Mendel (February 5, 1872 – December 9, 1935) was an American biochemist known for his pioneering work in the field of nutrition. He made significant contributions to the understanding of vitamins and amino acids and their roles in human health.

Early Life and Education

Lafayette Mendel was born in New York City, New York. He attended Yale University, where he earned his undergraduate degree in 1891. He continued his studies at Yale, receiving a Ph.D. in 1893 under the mentorship of Russell Henry Chittenden, a prominent biochemist.

Career and Research

Mendel joined the faculty at Yale University, where he worked for the rest of his career. He collaborated extensively with Thomas B. Osborne, a chemist at the Connecticut Agricultural Experiment Station. Together, they conducted groundbreaking research on the nutritional value of proteins and the importance of specific amino acids.

Vitamins

Mendel and Osborne's research was instrumental in the discovery of several essential vitamins. They were among the first to demonstrate the necessity of vitamin A and vitamin B in the diet. Their work laid the foundation for the field of vitaminology and significantly advanced the understanding of micronutrients.

Amino Acids

Mendel's research also focused on the role of amino acids in nutrition. He and Osborne identified the essential amino acids that the body cannot synthesize and must be obtained through diet. This work was crucial in the development of the concept of complete proteins and the importance of a balanced diet.

Legacy

Lafayette Mendel's contributions to biochemistry and nutrition have had a lasting impact on the field. His research has influenced dietary guidelines and the development of nutritional supplements. Mendel was a member of several prestigious scientific organizations, including the National Academy of Sciences.

Personal Life

Mendel married Alice R. Friend in 1900. They had no children. He passed away on December 9, 1935, in New Haven, Connecticut.
