Lafayette Mendel Net Worth

Lafayette Mendel was bornon February 05, 1872 in Delhi, New York, United States, United States, is Biochemist. Lafayette Mendel was an American biochemist who is known for making revolutionary discovery in the field of nutrition. He, together with Thomas B Osborne, studied the value of vitamins and proteins in daily diet as a means for healthy living. Through their research and experiments, they established amino acids and determined the importance of a healthy diet by incorporating vitamin A, vitamin B, lysine and tryptophan in the diet. They also established the modern concepts of nutrition. Through the studies, they revealed the ill effects that a diet devoid of vitamins can have. Did you know that deficiency of vitamin A will not just hamper our daily requirement of nutrition, but also lead us to xerophthalmia, a disease caused by lack of vitamin A? Right from the early years in life, Mendel showed an affinity towards science. Academically brilliant, he garnered for himself a scholarship that helped him gain admission at Yale University. Finishing his studies, he served at his alma mater, eventually becoming Sterling Professor in 1921. He published more than 100 papers in his lifetime, each detailing about his research and findings in the field of nutrition.

Biography/Timeline

1833

Mendel was born in Delhi, New York, son of Benedict Mendel, a merchant born in Aufhausen, Germany in 1833, and Pauline Ullman, born in Eschenau, Germany. His Father immigrated to the United States from Germany in 1851, his mother in 1870.

1891

At 15, he won a New York State scholarship. Mendel studied classics, economics and the humanities, as well as biology and chemistry at Yale University and graduated with honors in 1891.

1893

He then began graduate work at the Sheffield Scientific School on a fellowship and studied physiological chemistry under Russell Henry Chittenden. He finished his Ph.D. 1893 after only two years; his thesis topic was the study of the seed storage protein edestin extracted from hemp seed. Upon graduation, he began as an assistant at the Sheffield School in Physiological chemistry. He also studied in Germany and was made an assistant professor on his return in 1896. He became a full professor in 1903 with appointments in the Yale School of Medicine and the Yale Graduate School as well as Sheffield.

1910

With Chittenden, Mendel became one of the founders of the science of nutrition. Together with longtime collaborator Thomas B. Osborne he established essential amino acids. As early as 1910 he found an important growth factor...later to be known as vitamin B. In 1903, at age 31, he was appointed full professor of physiological chemistry. In promoting Mendel, Yale made him one of the first high-ranking Jewish professors in the United States. Capping his illustrious career Mendel was appointed Sterling Professor of Physiological Chemistry in 1921. Of the twenty professors to be designated Sterling professors in the decade following their inception in 1920, only two were selected before Mendel. Of the twenty, Mendel was the only Jew.

1913

Mendel and Osborne's most important work involved the use of carefully controlled studies on rats to study the necessary elements in a healthy diet. They discovered Vitamin A in 1913 in butter fat – independently discovered by Elmer McCollum and Marguerite Davis, who submitted their publication first, with both papers appearing in the same issue of the Journal of Biological Chemistry – as well as water-soluble vitamin B in milk. They showed, for Example, that a lack of Vitamin A in the diet led to xerophthalmia. They also established the importance of lysine and tryptophan in a healthy diet.

1916

Mendel wrote many articles and published Changes in the Food Supply and Their Relation to Nutrition (1916) and Nutrition, the Chemistry of Life (1923).

1917

Mendel married Alice R. Friend on July 29, 1917; they had no children. He died in 1935 of a heart condition after a long illness. His house in New Haven is a National Historic Landmark.

1921

Mendel received many honors during his career. He was made Sterling Professor at Yale in 1921. He was the first President of the American Institute of Nutrition. He was made a member of the National Academy of Sciences in 1913. He won the American Institute of Chemists Gold Medal in 1927 "for his outstanding contributions to chemistry". He won the Conné Medal of the Chemist's Club of New York in 1935 "for his outstanding chemical contributions to medicine".
