Melvin Calvin
Melvin Ellis Calvin (April 8, 1912 – 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. Early life and education 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 Mic ...

Priestley Medal
The Priestley Medal is the highest honor conferred by the American Chemical Society (ACS) and is awarded for distinguished service in the field of chemistry. Established in 1922, the award is named after Joseph Priestley, the discoverer of oxygen who immigrated to the United States of America in 1794. The ACS formed in 1876, spearheaded by a group of chemists who had met two years previously in Priestley's home. The Priestley Medal is commonly awarded to scientists who are advanced in their fields, as it is intended to commemorate lifetime achievement. When the ACS started presenting the Priestley Medal in 1923, they intended to award it every three years. This continued until 1944, when it became an annual award.

Carbon-14
Carbon-14, C-14, or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was discovered on February 27, 1940, by Martin Kamen and Sam Ruben at the University of California Radiation Laboratory in Berkeley, California. Its existence had been suggested by Franz N. D. Kurie, Franz Kurie in 1934. There are three naturally occurring isotopes of carbon on Earth: carbon-12 (), which makes up 99% of all carbon on Earth; carbon-13 (), which makes up 1%; and carbon-14 (), which occurs in trace amounts, making up about 1 or 1.5 atoms per 1012 atoms of carbon in the atmosphere. Carbon-12 and carbon-13 are both stable, while carbon-14 is unstable and has a half-life of 5,730 ± 40 years. Carbon-14 decays into nitrogen-14 () through bet ...

Sam Ruben
Samuel Ruben (born Charles Rubenstein; November 5, 1913 – September 28, 1943) was an American chemist who with Martin Kamen co-discovered the synthesis of the isotope carbon-14 in 1940. Early life Ruben was the son of Herschel and Frieda Penn Rubenstein – the name was officially shortened to Ruben in 1930. Young Sam developed a friendship with neighbor Jack Dempsey and became involved with a local boys' boxing club and later, when the family moved across the Bay to Berkeley, he was a successful basketball player at Berkeley High School (Berkeley, California). After achieving his B.S. in Chemistry at the University of California, Berkeley, he continued his studies there and was awarded a Ph.D. in physical chemistry in May 1938. He was immediately appointed instructor in the Chemistry Department, and became an assistant professor in 1941.

Martin Kamen
Martin David Kamen (August 27, 1913, Toronto – August 31, 2002, Montecito, California) was an American chemist who, together with Sam Ruben, co-discovered the synthesis of the isotope carbon-14 on February 27, 1940, at the University of California Radiation Laboratory, Berkeley. He also confirmed that all of the oxygen released in photosynthesis comes from water, not carbon dioxide, in 1941. Kamen was the first to use carbon-14 to study a biochemical system, and his work revolutionized biochemistry and molecular biology, enabling scientists to trace a wide variety of biological reactions and processes. Despite being blacklisted for nearly a decade on suspicion of being a security risk, Kamen went on to receive the Albert Einstein World Award of Science in 1989, and the U.S. Department of Energy's 1995 Enrico Fermi award for lifetime scientific achievement. Early life and education Kamen was born on August 27, 1913, in Toronto, the son of Russian Jewish immigrants. He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Russian Empire
The Russian Empire was an empire and the final period of the Russian monarchy from 1721 to 1917, ruling across large parts of Eurasia. It succeeded the Tsardom of Russia following the Treaty of Nystad, which ended the Great Northern War. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China. It also held colonies in North America between 1799 and 1867. Covering an area of approximately , it remains the third-largest empire in history, surpassed only by the British Empire and the Mongol Empire; it ruled over a population of 125.6 million people per the 1897 Russian census, which was the only census carried out during the entire imperial period. Owing to its geographic extent across three continents at its peak, it featured great ethnic, linguistic, religious, and economic diversity. From the 10th–17th centuries, the land ...

James Bassham
James Alan Bassham (November 26, 1922 – November 19, 2012) was an American scientist known for his work on photosynthesis. He received a B.S. degree in chemistry in 1945 from the University of California, Berkeley, earning his Ph.D. degree from Berkeley in 1949. His graduate studies were on the subject of carbon reduction during photosynthesis, working with Melvin Calvin in the Bio-Organic Chemistry Group of the Lawrence Radiation Laboratory at the University of California. He discovered, with Melvin Calvin and Andrew Benson, the Calvin-Benson-Bassham cycle. He continued his work as Associate Director of this group. Besides his work on the basic carbon reduction cycle of photosynthesis, Bassham conducted research on the biosynthetic paths leading from the cycle to the thermodynamics and kinetics of the carbon paths and the factors that control the flow of material and energy in this metabolic network.
