He also discovered that tritium similarly could be used for dating water, and therefore wine.

During World War II he worked in the Manhattan Project's Substitute Alloy Materials (SAM) Laboratories at Columbia University, developing the gaseous diffusion process for uranium enrichment.

After the war, Libby accepted professorship at the University of Chicago's Institute for Nuclear Studies, where he developed the technique for dating organic compounds using carbon-14.

Libby resigned from the AEC in 1959 to become Professor of Chemistry at University of California, Los Angeles (UCLA), a position he held until his retirement in 1976.

In 1962, he became the Director of the University of California statewide Institute of Geophysics and Planetary Physics (IGPP).

Willard Libby visited Lindau and lectured two times, first at the physics meeting in 1971 and then at the chemistry meeting 1974.

This is symptomatic, since his activities as radio-chemist really bridged the gap between physics and chemistry.

The most promising type was a barrier made of powdered nickel developed by Edward O.

Norris of the Jelliff Manufacturing Corporation and Edward Adler from the City College of New York, which became known as the "Norris-Adler" barrier by late 1942.

Signals from radioactive decay can then, e.g., show the path taken by the stable element through the human body.
