University of Chicago chemist Willard Libby (1908-80) develops the technique of radiocarbon dating. 

Radiocarbon dating originated with W. F. Libby (1955,1965) and is routinely applied in specialized laboratories of archaeology and in the environmental sciences held. Radiocarbon technique is based on the constant rate at which carbon-14 spontaneously decays. A or ratio can be determined by measuring the... 

The application of this technique for dating objects using 14C has led to a method that is more sensitive and precise than the classical Libby method of radiocarbon dating.

Radiometric dating As radioisotopes have a given half-life they can be used to calculate or date a sample. Referred to as radiometric dating (including carbon dating), it is possible on the basis of a measure of half-life of an isotope in a sample to determine its age or how long it has existed. Radiocarbon dating was discovered in 1949 by the American chemist, Willard Frank Libby, who was awarded the Nobel Prize in Chemistry in 1960 /or his method to use carbon-14 for age determination .

SINCE LIBBY S DEVELOPMENT of the radiocarbon dating method, which made the determination of absolute dates—or of dates with a known degree of precision—possible, archaeology has undergone a subtle and continuous transformation toward greater precision and reliance on quantitative data. Dating has become one of the milestones of modern ar-... 

The radiocarbon dating method was developed by Willard F. Libby and his coworkers James R. Arnold and Ernest C. Anderson between 1946 and 1949 at the University of Chicago. The now well-known physical model on which the method rests had been conceived by Libby during the period of his tenure with the Manhattan Project at Columbia University during World War II (1,2). The first critical test of the model... 

Radiocarbon dating has attracted considerable attention. Carbon-14 is produced in the upper atmosphere by cosmic-ray bombardment of nitrogen-14. It is oxidised to carbon dioxide and eventually absorbed and incorporated in the tissues of plants and animals. The time taken for a carbon atom to complete such a carbon-cycle and return to the upper atmosphere is, on average, about 500 years. As the half-life of is 5568 years, the specific activity of carbon in the carbon cycle is roughly constant. But carbon removed from this life-embracing cycle by conversion to, and retention in, a solid such as wood, bone or shell loses activity at a rate determined by the decay constant for Thus the specific activity of carbon in a rock, a fossil plant or bone, or ancient artifact gives its age (Libby, 1951). Measurements are not easy because of the low specific activities but are of considerable and improving accuracy. 

Libby published Radiocarbon Dating (1952), authored numerous scientific articles, and was a member of the editorial board of the Proceedings of the National Academy of Sciences and of Science.
