David Sidney Feingold
Introduction '''David Sidney Feingold''' (Hebrew דוד סידני פיינגולד; November 15, 1922 – September 26, 2019) was an American biochemist.
Biography Feingold was born in Chelsea, Massachusetts, United States in 1922.In 1944 he graduated from Massachusetts Institute of Technology with a bachelor's degree in chemistry. Following his graduation, he enlisted in the United States Navy. Feingold served on an Landing Ship, Tank in the Pacific for nine months, from 1945 to 1946.From 1947 to 1949 he continued his studies in chemistry at the Chemical Institute at the University of Zurich, in Switzerland.In 1949 he moved to Israel. Until 1950, he served in the scientific division of the Israeli Army as a second lieutenant. From 1950 to 1951, he worked at the Hadassah Hospital in Jerusalem. Between 1951 and 1956, Feingold was a student of biochemistry in Jerusalem. In 1956 he was awarded a Ph.D. from the Hebrew University of Jerusalem.Following receipt of his PhD he returned to the United States and served as a research assistant at the University of California from 1956 to 1960.In 1960 he moved to the University of Pittsburgh as an assistant professor in the department of biology. In 1966 he was appointed professor of microbiology at the University of Pittsburgh School of Medicine. He also served as an invited professor in Switzerland, Brazil, and Argentina, as well as at the University of Colorado. He taught until his retirement in 1993.He died in September 2019 at the age of 96.
Awards In 1957 Feingold was awarded the Israel Prize, in exact sciences, jointly with his research partner Shlomo Hestrin and their student Gad Avigad.
