(News) confirms that the settlement is indeed from the Iron Age, which fits with the writing of Greek historian Herodotus, who claimed that Pteria was sacked by Croesus, king of Lydia, 50 years after it was founded.Willard Frank Libby (December 17, 1908 – September 8, 1980) was an American physical chemist noted for his role in the 1949 development of radiocarbon dating, a process which revolutionized archaeology and palaeontology.He started the first Environmental Engineering program at UCLA in 1972, and as a member of the California Air Resources Board, he worked to develop and improve California's air pollution standards.On December 8, 1941, the day after the Japanese attack on Pearl Harbor brought the United States into World War II, Libby volunteered his services to Nobel Prize laureate Harold Urey.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.

Libby helped with the engineers from Kellex to produce a workable design for a pilot plant.Urey arranged for Libby to be given leave from the University of California and to join him at Columbia University to work on the Manhattan Project, the wartime project to develop atomic bombs, An atomic bomb required fissile material, and the fissile uranium-235 made up only 0.7 percent of natural uranium.The SAM Laboratories therefore had to find a way of separating kilograms of it from the more abundant uranium-238.Tests against sequoia with known dates from their tree rings showed radiocarbon dating to be reliable and accurate.The technique revolutionised archaeology, palaeontology and other disciplines that dealt with ancient artefacts.
