Yehuda Rav was born in 1930, in Vienna, Austria and grew up in Israel. He came in 1951 to the US for his undergraduate and graduate studies at Columbia University, majoring in mathematics and wrote a thesis in biological automata theory. He taught at Columbia University and Hofstra University before emigrating to France in 1967. From that date until his retirement in 1995, he was on the faculty of the University of Paris, Orsay Center. He has published numerous articles in logic, set theory, philosophy of mathematics, and history of cybernetics, as well as more than 200 reviews in Mathematical Reviews. He is still active in scholarly work, with a special interest in the neurocognitive sciences and evolutionary epistemology.
