And Libby himself, when he analyzed wood samples from trees once buried beneath glacial ice, documented that North America's last Ice Age ended approximately 11,000 years ago -- not 25,000 years ago as previously believed."This radiocarbon dating method was a transformative advance to archaeology and historical studies, allowing the determination of the age of archeological sites and objects without reliance on a knowledge of local customs and history," said Viresh Rawal, professor and chair of the Department of Chemistry.

"Libby's method remained the only way to measure carbon-14 in samples for several decades and was long considered the most accurate means of dating by carbon decay," said David Mazziotti, a UChicago chemistry professor who submitted the formal nomination of the site as a historic chemical landmark to the American Chemical Society.

Libby collaborated extensively with Oriental Institute archaeologist Robert Braidwood in conducting C-14 tests on artifacts of known age from Mesopotamia and Western Asia, including wood from an Egyptian mummy's casket.

Other tested samples included part of the deck of a funeral ship placed in the tomb of Sesostris III of Egypt, the heartwood of one of the largest redwood trees ever cut, and the linen wrapping one of the Dead Sea Scrolls.

This work enabled Libby and postdoctoral associate James Arnold to publish a carbon-14 atomic calendar in the Dec. They documented the viability of the technique with this article, which compared the ages of samples of known age with the ages as determined by their radiocarbon content.

The University announced Libby's results in a news release issued in connection with the article.

By this means, scientists may date objects as much as 50,000 years old.
