Andrew Benson

Andrew Alm Benson (September 24, 1917 – January 16, 2015) was an American biologist and a professor of biology at the University of California, San Diego, until his retirement in 1989. He is known for his work in understanding the carbon cycle in plants.

Early life and education Benson was born on September 24, 1917, in Modesto, California, the son of a rural physician of Swedish immigrant stock. He studied as an undergraduate and masters student at the University of California, Berkeley, where he learned optics from Luis Alvarez and worked in the chemistry lab of Glenn T. Seaborg. at Caltech, he worked under the supervision of Carl Niemann, conducting experiments on the fluorination of thyroxine; his later thesis work concerned "periodate and lead tetraacetate degradation of its vicinal amino glycol".

Research In work done from 1946 through 1953, along with Melvin Calvin and James Bassham, Benson elucidated the path of carbon assimilation (the photosynthetic carbon reduction cycle) in plants. The carbon reduction cycle is known as the Calvin cycle, which inappropriately ignores the contribution of Bassham and Benson. Many scientists refer to the cycle as the Calvin–Benson Cycle, Benson–Calvin, and some call it the Calvin–Benson–Bassham (or CBB) Cycle. the American Academy of Arts and Sciences in 1981, and the Norwegian Academy of Science and Letters in 1984. He also received the Sugar Research Foundation Award in 1950 and the Stephen Hales Prize of the American Society of Plant Biologists in 1972 for his discovery of ribulose as a product of the carbon cycle. In 2007, a special issue of Photosynthesis Research was dedicated to him in honor of his 90th birthday.

Benson is a major figure (at Calvin's expense) in episode 2, dealing with photosynthesis, of the history of botany presented in 2011 on BBC Four. The series is presented by Timothy Walker and is entitled Botany—A Blooming History.
