Hubert Lederer Dreyfus (born October 15, 1929)
is an American philosopher and professor of philosophy at the University of California, Berkeley.
His main interests include phenomenology, existentialism and the philosophy of both psychology and literature, as well as the philosophical implications of artificial intelligence. Dreyfus is known for his exegesis of Martin Heidegger, which critics labeled "Dreydegger".
Dreyfus is featured in Tao Ruspoli's film Being in the World. He was elected a Fellow of the American Academy of Arts and Sciences in 2001 and is a recipient of the Harbison Prize for Outstanding Teaching at UC Berkeley. Erasmus University awarded Dreyfus an honorary doctorate "for his brilliant and highly influential work in the field of artificial intelligence, and for his equally outstanding contributions to the analysis and interpretation of twentieth century continental philosophy".
A number of his students have gone on to hold tenured positions in leading American philosophy departments while working on themes related to Heidegger and phenomenology, including William Blattner,Taylor Carman, John Haugeland, Sean Dorrance Kelly, John Richardson, Charles Siewert, Iain Thomson, and Mark Wrathall.
