Radiocarbon dating was invented in the 1950s by the american chemist willard f libby and a few of his students at the university of chicago: in 1960, he won a nobel prize in chemistry for the invention. Carbon-14 dating radio-carbon dating is a method of obtaining age estimates on organic materials the word estimates is used because there is a significant amount of uncertainty in these measurements. Willard libby invented the carbon dating technique in the early 1950’s he calculated the amount of carbon-14 in the atmosphere today (about 0000765%), and assumed there would be the same amount found in living plants or animals since the plants breathe co2 and animals eat plants. Carbon-14 dating: carbon-14 dating, , method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14) carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the earth’s atmosphere the neutrons required for this reaction are produced by cosmic.
