Libby won the Nobel Prize for Chemistry in 1960, for introducing a dating methodology using radioactive carbon-14, a long-lived, natural beta-emitting radioisotope emitted in minute quantities by all living things.
Renfrew (1973) called it 'the radiocarbon revolution' in describing its impact upon the human sciences.
Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species.
First tested and calibrated with material found in 4,000-year-old Egyptian tombs, carbon-dating has been used on progressively older and older relics, and has become an extremely important tool for anthropologists, archaeologists, geologists, and other earth scientists.
Carbon-14 dating is now believed to be accurate for finding the age of materials up to 70,000 years old, with a margin of error of about ten percent.
"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.
After the war ended, Libby returned to his research in nuclear chemistry at the department of chemistry and Institute for Nuclear Studies at the University of Chicago.
Libby, a physical chemist, is best known for leading a team at the University of Chicago that developed a technology in the late 1940s—radiocarbon dating—that revolutionized how we understand the history of the earth and its living species.
It has successfully determined the age of artifacts up to 50,000 years ago.
Then war will become inconceivable." He also studied hot atom chemistry, isotope tracer work and other tracer techniques, and the use of natural tritium in hydrology and geophysics, and served for several years on the US Atomic Energy Commission, where he advocated peaceful uses for atomic energy. 20-Jun-1992, two daughters)Daughter: Janet Eva (twin, b.
