American biochemist

Melvin Ellis Calvin (April 8, 1911 – January 8, 1997) was an American biochemist known for discovering the Calvin cycle along with Andrew Benson and James Bassham, for which he was awarded the 1961 Nobel Prize in Chemistry. He spent most of his five decade career at the University of California, Berkeley.

Melvin Calvin was born in St. Paul, Minnesota, the son of Elias Calvin and Rose Herwitz, Jewish immigrants from the Russian Empire (now known as Lithuania and Georgia). At an early age, Melvin Calvin’s family moved to Detroit, MI where his parents ran a grocery store to earn their living. Melvin Calvin was often found exploring his curiosity by looking through all of the products that made up their shelves. Something he quickly recognized is the importance of chemistry to everyday products and our daily lives. After he graduated from Central High School in 1928, he went on to study at Michigan College of Mining and Technology (now known as Michigan Technological University) where he received the school’s first Bachelors of Science in Chemistry. He went on to earn his Ph. D. at the University of Minnesota in 1935. While under the mentorship of George Glocker, he studied and wrote his thesis on the electron affinity of halogens. He was invited to join the lab of Michael Polanyi as a Post Doctoral student at the University of Manchester. The two years he spent at the lab were focused on studying the structure and behavior of organic molecules. In 1942, He married Marie Genevieve Jemtegaard,

On a visit to the University of Manchester, Joel Hildebrand, the director of UC Radiation Laboratory, invited Calvin to join the faculty at the University of California, Berkeley. This made him the first non Berkeley graduate hired by the chemistry department in +25 years. He invited Calvin to push forward in radioactive carbon research because "now was the time". The process is part of the photosynthesis cycle. It was given the name the Calvin–Benson–Bassham Cycle, named for the work of Melvin Calvin, Andrew Benson, and James Bassham. There were many people who contributed to this discovery but ultimately Melvin Calvin led the charge (see below). In 1963, Calvin was given the additional title of Professor of Molecular Biology. He was founder and Director of the Laboratory of Chemical Biodynamics, known as the “Roundhouse”, and simultaneously Associate Director of Berkeley Radiation Laboratory, where he conducted much of his research until his retirement in 1980. 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.

The circular laboratory known as the “Roundhouse”  was designed to facilitate collaboration between students and visiting scientists in Calvin’s lab. Benson himself has also mentioned being fired by Calvin, and has complained about not being mentioned in his autobiography.
