Today (April 8, 1911) is the birthday of Melvin Calvin, the Nobel Prize - winning American chemist who discovered the 'Calvin cycle' in photosynthesis.

Today (April 8, 1911) is the birthday of Melvin Calvin, the Nobel Prize-winning American chemist who discovered the 'Calvin cycle' in photosynthesis.

 

Melvin Ellis Calvin was born on April 8, 1911, in Minnesota, the USA, the son of Elias Calvin and Rose Herwits. His family moved to Detroit when Calvin was a small child. He graduated from Central High School in 1928. He received his bachelor's degree in science from the Michigan College of Mining and Technology (now Michigan University of Technology) in 1931, and his doctorate in chemistry from the University of Minnesota in 1935. For the next four years, he did post-doctoral work at the University of Manchester. In 1942 Mary married Geneva Gemdecard.

Calvin became a faculty member at the University of California, Berkeley in 1937. In 1947 he was promoted to professor of chemistry. Using the carbon-14 isotope as a tracer, Calvin, Andrew Benson and James Basham mapped out the complete path of carbon travel. During photosynthesis, the plant begins to absorb atmospheric carbon dioxide and converts it into carbohydrates and other organic compounds. In doing so, Calvin, Benson, and Basham showed that sunlight acts on chlorophyll in a plant to stimulate the production of organic compounds, rather than carbon dioxide, as previously believed. Sometimes called the Calvin-Benson-Basham cycle. Recipient of the 1961 Nobel Prize in Chemistry.

 

In the 1950s he was one of the first members of the Public Organizations Research Association. In 1963 he was given the additional responsibility of Professor of Molecular Biology. He was the founder and director of the Laboratory of Chemical Biodynamics and at the same time the Associate Director of the Berkeley Radiation Laboratory. There he continued his research until his retirement in 1980. In his final year, he spent many years exploring the use of oil-producing plants as a source of renewable energy, experimenting with the chemical evolution of life and publishing a book on chemical evolution, published in 1969.

In 1958 he was elected a foreign member of the Royal Netherlands Academy of Arts and Sciences. In 1959 he was elected a member of the German Academy of Sciences Leopoldina. In 1971, Calvin was awarded an honorary doctorate (LLD) from Whittier College. Calvin was featured in the 2011 volume of the American Scientists Collection of American Postage Stamps with Asa Gray, Maria Copper-Meyer and Servo Ochoa. Melvin Calvin, who discovered the 'Calvin cycle', passed away on January 8, 1997, in the United States, California at the age of 85.
