Calvin was the son of immigrant parents.
His father was from Kalvaria, Lithuaniaso the Ellis Island immigration authorities renamed him Calvin; his mother was from Russian Georgia. Soon after his birth, the family moved to DetroitMichigan, where Calvin showed an early interest in scienceespecially chemistry and physics.
Few chemistry courses were offered, so he enrolled in mineralogy, geology, paleontology, and civil engineering courses, all of which proved useful in his later interdisciplinary scientific research.
Following his sophomore year, he interrupted his studies for a year, earning money as an analyst in a brass factory. With a Rockefeller Foundation grant, he researched coordination catalysis, activation of molecular hydrogenand metalloporphyrins porphyrin and metal compounds at the University of Manchester in England with Michael Polanyi, who introduced him to the interdisciplinary approach.
In Calvin joined the faculty of the University of CaliforniaBerkeley, as an instructor. He was the first chemist trained elsewhere to be hired by the school since At Berkeley, Calvin continued his work on hydrogen activation and began work on the colour of organic compoundsleading him to study the electronic structure of organic molecules.
In the early s, he worked on molecular geneticsproposing that hydrogen bonding is involved in the stacking of nucleic acid bases in chromosomes. During World War IIhe worked on cobalt complexes that bond reversibly with oxygen to produce an oxygen-generating apparatus for submarines or destroyers.
In the Manhattan Projecthe employed chelation and solvent extraction to isolate and purify plutonium from other fission products of uranium that had been irradiated.
Although not developed in time for wartime use, his technique was later used for laboratory separations. Seaborg as best man. The married couple collaborated on an interdisciplinary project to investigate the chemical factors in the Rh blood group system.
This was her first chemical laboratory experience but not her last by any means. Following the oil embargo after the Arab-Israeli Warthey sought suitable plants, e. In Calvin began his Nobel prize-winning work on photosynthesis. This enabled him to identify most of the chemical reactions in the intermediate steps of photosynthesis—the process in which carbon dioxide is converted into carbohydrates.
Also using isotopic tracer techniques, he followed the path of oxygen in photosynthesis. This was the first use of a carbon tracer to explain a chemical pathway.
Pathway of carbon dioxide fixation and reduction in photosynthesis, the Calvin cycle. The diagram represents one complete turn of the cycle, with the net production of one molecule of glyceraldehydephosphate Gal3P. This three-carbon sugar phosphate usually is converted to either sucrose or starch.
This circular building contained open laboratories and numerous windows but few walls to encourage the interdisciplinary interaction that he had carried out with his photosynthesis group at the old Radiation Laboratory. He directed this laboratory until his mandatory age retirement inwhen it was renamed the Melvin Calvin Laboratory.
Although officially retired, he continued to come to his office until to work with a small research group. Calvin was the author of more than articles and 7 books, and he was the recipient of several honorary degrees from U. National Medal of Sciencethe highest U.Updated world stock indexes.
