Willard Frank Libby was an American physical chemist who was awarded the ‘Nobel Prize’ in Chemistry in 1960 for developing the technique of radiocarbon dating or carbon-14 dating, a process that proved to be extremely beneficial in the field of palaeontology and archaeology. He is also noted for developing another radioactive dating procedure using a radioactive isotope of hydrogen called tritium for dating substances like water and wine. Libby examined radioactive elements and thereby developed sensitive Geiger counter, an instrument that measures weak natural and artificial radioactivity. At the time of the ‘Second World War’ he contributed in developing the procedure of gaseous diffusion for uranium enrichment while working for the ‘Manhattan Project' at the ‘Columbia University’. He served as a Professor at the ‘Institute for Nuclear Studies’ of the ‘University of Chicago’ and later as Professor of Chemistry at ‘University of California’. He was a member of ‘General Advisory Committee’ of ‘Atomic Energy Commission’ and later inducted as Atomic Energy Commissioner. He became Director of the ‘Institute of Geophysics and Planetary Physics’ at the ‘University of California’. He took part in the ‘Atoms for Peace’ program, supported the administration for atmospheric nuclear testing and advocated measures to combat the anticipated nuclear threat of the Soviet Union.
