For his contributions to the team that developed this process, Libby was awarded the in 1960. A 1927 chemistry graduate of the , from which he received his doctorate in 1933, he studied radioactive elements and developed sensitive to measure weak natural and artificial radioactivity. During he worked in the 's Substitute Alloy Materials SAM Laboratories at , developing the process for. After the war, Libby accepted professorship at the 's , where he developed the technique for dating organic compounds using. He also discovered that similarly could be used for dating water, and therefore wine. In 1950, he became a member of the General Advisory Committee GAC of the AEC. He was appointed a commissioner in 1954, becoming its sole scientist. He sided with on pursuing a crash program to develop the , participated in the program, and defended the administration's atmospheric. Libby resigned from the AEC in 1959 to become Professor of Chemistry at UCLA , a position he held until his retirement in 1976. In 1962, he became the Director of the statewide Institute of and Planetary Physics IGPP. He started the first Environmental Engineering program at UCLA in 1972, and as a member of the , he worked to develop and improve California's air pollution standards. Willard Frank Libby was born in , on December 17, 1908, the son of farmers Ora Edward Libby and his wife Eva May née Rivers. He had two brothers, Elmer and Raymond, and two sisters, Eva and Evelyn. Libby began his education in a two-room Colorado schoolhouse. When he was five, Libby's parents moved to. He attended , in , from which he graduated in 1926. Libby, who grew to be 6 feet 2 inches 188 cm tall, played on the high school team. Independently of the work of and Max Pahl, he discovered that the natural long-lived isotopes of primarily decay by emission of. Libby was appointed Instructor in the Department of Chemistry at the , in 1933. He became an of Chemistry there in 1938. He spent the 1930s building sensitive to measure weak natural and artificial radioactivity. He joined Berkeley's chapter of in 1941. That year he was awarded a , and elected to work at. On December 8, 1941, the day after the brought the United States into , Libby volunteered his services to Nobel Prize laureate. Urey arranged for Libby to be given leave from the University of California and to join him at to work on the , the wartime project to develop , at what became its Substitute Alloy Materials SAM Laboratories. During his time in the New York City area, Libby was a resident of. Over the next three years, Libby worked on the process for. An atomic bomb required material, and the fissile made up only 0. The SAM Laboratories therefore had to find a way of separating kilograms of it from the more abundant. Gaseous diffusion worked on the principle that a lighter gas diffuses through a barrier faster than a heavier one at a rate inversely proportional to its molecular weight. But the only known gas containing uranium was the highly corrosive , and a suitable barrier was hard to find. Through 1942, Libby and his team studied different barriers and the means to protect them from corrosion from the uranium hexafluoride. The most promising type was a barrier made of powdered developed by Edward O. In addition to developing a suitable barrier, the SAM Laboratories also had to assist in the design of a gaseous separation plant, which became known as. Libby helped with the engineers from to produce a workable design for a pilot plant. Libby conducted a series of tests that indicated that the Norris-Adler barrier would work, and he remained confident that with an all-out effort, the remaining problems with it could be solved. Although doubts remained, construction work began on the K-25 full-scale production plant in September 1943. As 1943 gave way to 1944, many problems remained. Tests began on the machinery at K-25 in April 1944 without a barrier. Attention turned to a new process developed by Kellex. Finally, in July 1944, Kellex barriers began to be installed in K-25. K-25 commenced operation in February 1945, and as cascade after cascade came online, the quality of the product increased. By April 1945, K-25 had attained a 1. Uranium partially enriched in K-25 was fed into the at to complete the enrichment process. Construction of the upper stages of the K-25 plant was cancelled, and Kellex was directed to instead design and build a 540-stage side feed unit, which became known as K-27. The last of K-25's 2,892 stages commenced operation in August 1945. On August 5, K-25 starting producing feed enriched to 23 percent uranium-235. K-25 and K-27 achieved their full potential only in the early postwar period, when they eclipsed the other production plants and became the prototypes for a new generation of plants. Enriched uranium was used in the bomb employed in the on August 6, 1945. He returned to his pre-war studies of radioactivity. In 1939, Serge Korff had discovered that generated in the upper atmosphere. Libby realized that when plants and animals die they cease to ingest fresh carbon-14, thereby giving any organic compound a built-in nuclear clock. He published his theory in 1946, and expanded on it in his monograph Radiocarbon Dating in 1955. He also developed sensitive radiation detectors that could use the technique. Tests against with known dates from their tree rings showed to be reliable and accurate. The technique revolutionised , and other disciplines that dealt with ancient artefacts. He also discovered that similarly could be used for dating water, and therefore wine. AEC Chairman appointed Libby to its influential General Advisory Committee GAC in 1950. In 1954, he was appointed an AEC commissioner by on the recommendation of Dean's successor,. Libby and his family moved from Chicago to He brought with him a truckload of scientific equipment, which he used to establish a laboratory at the there to continue his studies of. Staunchly conservative politically, he was one of the few scientists who sided with rather than during the debate on whether it was wise to pursue a crash program to develop the. As a commissioner, Libby played an important role in promoting Eisenhower's program, and was part of the United States delegation at the Geneva Conferences on Peaceful Uses of Atomic Energy in 1955 and 1958. As the only scientist among the five AEC commissioners, it fell to Libby to defend the Eisenhower administration's stance on atmospheric. He argued that the dangers of radiation from nuclear tests were less than that from chest X-rays, and therefore less important than the risk of having an inadequate nuclear arsenal, but his arguments failed to convince the scientific community or reassure the public. In January 1956, he publicly revealed the existence of , a series of research studies to ascertain the impact of radioactive fallout on the world's population that he had initiated in 1953 while serving on the GAC. By 1958, even Libby and Teller were supporting limits on atmospheric nuclear testing. Libby resigned from the AEC in 1959, he became Professor of Chemistry at UCLA , a position he held until his retirement in 1976. He taught honors freshman chemistry. In 1962, he became the Director of the statewide Institute of and Planetary Physics IGPP , a position he also held until 1976. His time as director encompassed the and the lunar landings. Libby started the first Environmental Engineering program at UCLA in 1972. As a member of the , he worked to develop and improve California's air pollution standards. He established a research program to investigate with the idea of reducing emissions from motor vehicles through more complete fuel combustion. The election of as president in 1968 generated speculation that Libby might be appointed as Presidential Science Advisor. There was a storm of protest from scientists who felt that Libby was too conservative, and the offer was not made. Although Libby retired and became a in 1976, he remained professionally active until his death in 1980. Libby was an elected member of the , the , and the. In addition to the Nobel Prize, he received numerous honors and awards, including Columbia University's Chandler Medal in 1954, the Remsen Memorial Lecture Award in 1955, the Bicentennial Lecture Award from the and the Nuclear Applications in Chemistry Award in 1956, the 's in 1957, the 's in 1958, the from and the in 1959, the 's in 1961, the in 1970, and the Lehman Award from the in 1971. He was elected a member of the in 1950. His 1947 paper on radiocarbon dating was honored by a Citation for Chemical Breakthrough Award from the Division of History of Chemistry of the American Chemical Society presented to the University of Chicago in 2016. In 1940, Libby married Leonor Hickey, a teacher. They had twin daughters, Janet Eva and Susan Charlotte, who were born in 1945. In 1966 Libby divorced Leonor and married , a distinguished who was one of the original builders of , the world's first. She joined him at UCLA as a professor of in 1973. Through this second marriage he acquired two stepsons, the children of her first marriage. Libby died at the in on September 8, 1980, from a blood clot in his lung complicated by.
