'Melvin Ellis Calvin' (
April 8,
1911) is a
American chemist most famed for discovering the
Calvin cycle (along with
Andrew Benson), for which he was awarded the 1961
Nobel Prize in Chemistry. He spent virtually all of his five-decade career at the University of California, Berkeley.
Born in
Saint Paul, Minnesota, the son of
Jewish immigrants. His father was
Lithuanian and his mother Georgian. Calvin earned his Bachelor of Science from the
Michigan College of Mining and Technology (now known as
Michigan Tech University) in 1931 and his
Ph.D. in chemistry from the
University of Minnesota in 1935. He then spent the next four years doing postdoctoral work at the
University of Manchester. He married Genevieve Jemtegaard in 1942, and they had three children, two daughters and a son.
Calvin joined the faculty at the
University of California, Berkeley in 1937 and was promoted to Professor of Chemistry in 1947. In 1963 he was given the additional title of Professor of Molecular Biology. He was founder and Director of the Laboratory of Chemical Biodynamics and simultaneously Associate Director of
Berkeley Radiation Laboratory, where he conducted much of his research until his retirement in 1980.
Using the
carbon-14 isotope as a tracer, Calvin and his team mapped the complete route that carbon travels through a plant during
photosynthesis, starting from its absorption as atmospheric carbon dioxide to its conversion into carbohydrates and other organic compounds. In doing so, the Calvin group showed that sunlight acts on the
chlorophyll in a plant to fuel the manufacturing of organic compounds, rather than on
carbon dioxide as was previously believed. In his final years of active research, he studied the use of oil-producing plants as renewable sources of energy. He also spent many years testing the chemical evolution of life and wrote a book on the subject that was published in 1969. Calvin also researched
organic geochemistry,
chemical carcinogenesis and analysis of
moon rocks.
He served on the
Science Advisory Committee under
Presidents Kennedy and
Johnson and the Advisory Group to the
Office of Science and Technology Policy of the Executive Office of the President. He was elected to the
National Academy of Sciences, with which he was chairman of the Committee on Science and Public Policy, the
Royal Society of London, the
Japan Academy, and the
Royal Netherlands Academy of Sciences.
In addition to the 1961 Nobel Prize in chemistry, his awards included the
National Medal of Science, which he received in 1989, the
Priestley Medal from the American Chemical Society, the
Davy Medal from the
Royal Society of London, and the
Gold Medal from the
American Institute of Chemists.
