Professor Alfred Ivry died yesterday at the age of 91. A graduate of Brooklyn College, Brandeis and Oxford, he taught over the years at Cornell, Ohio State, Brandeis and NYU, where he was the Skirball Professor of Jewish Thought until his retirement in 2005. His nine books and hundred-some articles contribute both to Jewish and Islamic scholarship, in Hebrew and Arabic, ranging from careful scholarly editions to introductory guides, as for instance his Philosophical Guide to Maimonides’ Guide, published by Univ. of Chicago Press in 2016.
