Extractions: Willard Libby (b. Dec. 17, 1908, Grand Valley, Colo., U.S.d. Sept. 8, 1980, Los Angeles, Calif.), American chemist whose technique of carbon-14 (or radiocarbon) dating provided an extremely valuable tool for archaeologists, anthropologists, and earth scientists. For this development he was honoured with the Nobel Prize for Chemistry in 1960. Libby received his Ph.D. from the University of California, Berkeley, where he was a member of the faculty from 1933 to 1945. He was with the Institute for Nuclear Studies at the University of Chicago (1945-59) and then was professor of chemistry at the University of California, Los Angeles, until his death. While associated with the Manhattan Project (1941-45), Libby helped develop a method for separating uranium isotopes, an essential step in the creation of the atomic bomb. In 1946 he showed that tritium, the heaviest isotope of hydrogen, was produced by cosmic radiation. The following year he and his students developed the carbon-14 dating technique. This technique is used to date material derived from former living organisms as old as 50,000 years. It measures small amounts of radioactivity from the carbon-14 in organic or carbon-containing materials and is able to identify older objects as those having less radioactivity. Libby also served on the U.S. Atomic Energy Commission (1955-59) and wrote Radiocarbon Dating

Grand Valley, Colorado, December 17, 1908, d. Los Angeles, September 8, 1980] In 1947 Libby developed dating of artifacts based on carbon-14, a radioactive isotope created by sunlight acting on atmospheric nitrogen. The ratio of carbon-14 to stable carbon-12 is nearly constant in air and maintained by living organisms plants incorporate carbon during photosynthesis and animals feed on plants or other animals. After death, however, no more atmospheric carbon is consumed, so reduction in carbon-14 (half-life 5730 years) can measure the time since death. Dictionary Lib·by lÄb Willard Frank American chemist.

Extractions: Willard Libby was an American Chemist, best known for his development of Carbon 14 (radiocarbon) dating techniques. Libby was born Dec. 17, 1908 in Grand Valley, Colorado. He obtained his Ph.D. from the University of California-Berkeley University of Chicago . He also conducted research there at the Institute of Nuclear Studies until 1959. Libby then found himself back at the University of California as Director of the Institute of Geophysics and Planetary Physics. He served in that capacity until his death. In 1947, Libby and his students at the Institute for Nuclear Studies developed the method of C14 dating using a highly sensitive Geiger counter. Carbon 14 is an unstable radioactive isotope that decays at a measurable rate upon the death of an organism. Libby was able to determine the age of organic artifacts by measuring the amount of remaining C14. He tested his process on objects of known age, such as timbers from Egyptian tombs. The tests proved reliable and it was assumed that this technique was accurate for objects up to 50,000 years of age. Later, this was extended to 70,000 years. Radiocarbon Dating Libby died Sept. 8, 1980 in Los Angeles of a lung ailment. He was cremated.

Extractions: Libby was born in Grand Valley, Colorado, and studied at the University of California, Berkeley. During World War II he worked on the development of the atomic bomb (the Manhattan Project). In 1945 he became professor at the University of Chicago's Institute for Nuclear Studies. He was a member of the US Atomic Energy Commission 1954-59, and then became director of the Institute of Geophysics at the University of California. Having worked on the separation of uranium isotopes for producing fissionable uranium-238 for the atomic bomb, he turned his attention to carbon-14, a radioactive isotope that occurs in the tissues of all plants and animals, decaying at a steady rate after their death. He and his co-workers accurately dated ancient Egyptian relics by measuring the amount of radiocarbon they contained, using a sensitive Geiger counter. By 1947 they had developed the technique so that it could date objects up to 50,000 years old.
