The opening as it read in October 6, 2023

Isadore Twersky Isadore Twersky (also known as Yitzhak Asher Twersky , October 9, 1930 – October 12, 1997) was an Orthodox rabbi and Hasidic Rebbe , and university professor who held the position as Nathan Littauer Professor of Hebrew Literature and Philosophy at Harvard University , a chair previously held by Harry Austryn Wolfson . Twersky was an internationally recognized authority on Rabbinic literature and Jewish philosophy . He was especially known as an international expert in the writings and influence of the 12th-century Jewish legalist and philosopher Maimonides , and Abraham ben David , the Rabad of Posquieres. His best-known works are, An Introduction to the Code of Maimonides (Mishneh Torah) , and the more popular anthology, A Maimonides Reader, as well as Rabad of Posquieres: A Twelfth-Century Talmudist, which was based on his doctorate work. He was the editor of the Harvard Studies in Medieval Jewish History and Literature (in three volumes), won a Guggenheim Fellowship in 1989, and was a fellow of both the American Academy for Jewish Research and the American Academy of Arts and Sciences . According to Hacker (2005) , Twersky can best be characterized as a "historian of ideas and a researcher of the intellectual history of the Jews," and would presumably have considered himself as such.
