Martin Rodbell

Martin Rodbell (December 1, 1925 – December 7, 1998) was an American biochemist and molecular endocrinologist who is best known for his discovery of G-proteins. He shared the 1994 Nobel Prize in Physiology or Medicine with Alfred G. Gilman for "their discovery of G-proteins and the role of these proteins in signal transduction in cells." Biography Rodbell was born in Baltimore, Maryland, the son of Shirley (née Abrams) and Milton Rodbell, a grocer. His family was Jewish. After graduating from the Baltimore City College high school, he entered Johns Hopkins University in 1943, with interests in biology and French existential literature. In 1944, his studies were interrupted by his military service as a U.S. Navy radio operator during World War II. He returned to Hopkins in 1946 and received his B.S. in biology in 1949. In 1950, he married Barbara Charlotte Ledermann, a former friend of Margot Frank, diarist Anne Frank's older sister. Martin and Barbara had four children. Rodbell received his Ph.D. in biochemistry at the University of Washington in 1954. He did post-doctoral work at the University of Illinois at Urbana-Champaign from 1954 to 1956. In 1956, Rodbell accepted a position as a research biochemist at the National Heart Institute, part of the National Institutes of Health, in Bethesda, Maryland. In 1985, Rodbell became Scientific Director of the NIH's National Institute of Environmental Health Sciences in Research Triangle Park, North Carolina where he worked until his retirement in 1994. He was also adjunct professor of Cell Biology at Duke University (from 1991 to 1998) and adjunct professor of pharmacology at the University of North Carolina at Chapel Hill. He died in Chapel Hill of multiple organ failure after an extended illness. Research Reflecting the increasingly common analogies between computer science and biology in the 1960s, Rodbell believed that the fundamental information processing systems of both computers and biological organisms were similar. He asserted that individual cells were analogous to cybernetic systems made up of three distinct molecular components: discriminators, transducers, and amplifiers (otherwise known as effectors).
