Believed that the Earth
was 4.55 or 4.6 billion
years old. Worked with meteorites AND the Earth, he came up with the most accurate age of the Earth of his time, and his figure remained unchanged for 50 years! This is the Canyon Diablo Meteorite. Where? Short(ish) Biography Clair (Pat) Cameron Patterson was born on June 2, 1922, and died on December 5, 1995. Born in Mitchelville, Iowa, and graduated college, with a degree in chemistry at Grinnell, in Iowa, where he met Lorna (Laurie) McCleary . He then recieved his PhD at the University of Iowa. From there, he and his wife moved to the University of Iowa, where he did an M.A. in molecular spectroscopy. Both were then sent to work on the Manhattan Project, first at the University of Chicago and then at Oak Ridge, Tennessee, where he encountered mass spectrometry. Post war they returned to Chicago where Laurie took a research job as an infrared spectroscopist to support Pat while he did a Ph.D. at the University of Chicago under Harrison Brown. After a year at Chicago, Pat moved with Brown to the Division of Geology (The Division of Geological and Planetary Sciences) at Caltech in 1952 as founding members of its geochemistry program. Pat remained at Caltech for the rest of his life. The couple had four children. Not, Available. "Biography."

A technique used to date materials based on a knowledge of the decay rates of naturally occurring isotopes, and the current abundances. It is the principal source of information about the age of the Earth and a significant source of information about rates of evolutionary change Here... is... Clair... Keena Strope
