Willard Frank Libby 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.

For this work Libby was awarded the 1960 Nobel Prize for Chemistry. His work also includes the study of the heavy-hydrogen isotope tritium.
