Keith Lehrer was born January 10, 1936, in Minneapolis, Minnesota. He attended the University of Minnesota from 1953 to 1957, earning his BA in Philosophy magna cum laude. His teachers at Minnesota included Alan Donagan, John Hospers, Michael Scriven, Mary Shaw, May Brodbeck, Herbert Feigel, and Wilfred Sellers. Lehrer went on earn his AM in 1959 and his PhD in 1960, both in philosophy, at Brown University, where his teachers included Roderick Chisholm, John Ladd, John Lenz, Stephan K(rner, Vincent Thomas, Wesley Salmon, and Richard Taylor. Chisholm supervised Lehrer's master's thesis on epistemology, and Taylor supervised Lehrer's doctoral dissertation on free will. Chisholm's and Taylor's continuing support were not due to Lehrer's agreement with their positions: Lehrer was then and continues to be a coherence theorist in epistemology, whereas Chisholm was a foundationalist, and Lehrer has always endorsed compatibilism, whereas Taylor was a libertarian.
