Professor Willard Libby has been selected to be the prize-winner for his method of age determination of materials of biological origin by use of carbon-14 as a measurer of time.

His method has obtained widespread use and has become indispensable in archaeology, geology, geophysics and other sciences.

During the late 1950s, Libby and physicist ’s petition for a ban on nuclear weapons.

To prove the survivability of nuclear war, Libby built a fallout shelter at his house, an event that was widely publicized.

In about one million million of these carbon atoms, there is only one which has an atomic weight of 14.

But nevertheless, this ratio can be determined, for carbon-14 is a radioactive isotope and manifests itself by its radiation.

Fortunately, it is so simple - which is probably not always the case with chemical research distinguished with the Nobel Prize - that everyone should be able to understand the conditions and principles for its execution.

In 1946, Libby proposed this groundbreaking idea in the journal Physical Review.

Known as radiocarbon dating, this method provides objective age estimates for carbon-based objects that originated from living organisms.

The “radiocarbon revolution” made possible by Libby’s discovery greatly benefitted the fields of archaeology and geology by allowing practitioners to develop more precise historical chronologies across geography and cultures.

In 1941 Libby received a Guggenheim fellowship to work at , Los Angeles, and director of its Institute of Geophysics and Planetary Physics (from 1962) until his death.

He was the recipient of numerous honours, awards, and honourary degrees.
