According to Diane Grob Schmidt, the immediate past president of the ACS, every subject submitted for landmark consideration must fulfill three criteria: it must be more than 25 years old, it must represent a “seminal achievement” in chemistry, and it must have a significant contribution to society.As she presented the plaque, Schmidt said that beyond fulfilling the criteria, Libby’s work is “a fantastic example of the transforming power of chemistry” because of its profound effects on not only areas of study but also “on ourselves” by providing a fuller understanding of our past.The age of organic objects can be calculated by comparing the ratio of remaining C in a sample to the atmospheric content at the time of death.This method had a tremendous impact on archaeology, as it allows to accurately date artifacts from a large timescale. He joined UC Berkeley's Radiation Laboratory, working with Sam Ruben.Radiocarbon dating has been one of the most significant discoveries in 20th century science.

The discovery is the 80th National Historic Chemical Landmark to be designated by the American Chemical Society (ACS).

Writing of the European Upper Palaeolithic, Movius (1960) concluded that "time alone is the lens that can throw it into focus".

The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.

For this discovery, Libby was awarded the 1960 Nobel Prize in Chemistry. He stayed at UC Berkeley, working on chemistry, nuclear physics, and the elucidation of biochemical reation pathways under Ernest O. Their experiments using born in Toronto, Canada, in 1913, studied chemistry at the University of Chicago, IL, USA, where he received his Ph. Kamen was assigned to the Manhattan Project in 1943, working at Oak Ridge Laboratory, TN.

born in 1913, studied chemistry at the University of California, Berkeley, where he received his Ph. After his return to Berkeley, he faced allegations of being a spy because his parents imigrated from Russia and lost his position.Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species.
