Harry Austryn Wolfson (November 2, 1887 – September 20, 1974) was a scholar, philosopher, and historian at Harvard University, and the first chairman of a Judaic Studies Center in the United States. He is best known for his seminal work on the Jewish philosopher Philo, but he also authored an astonishing variety of other works on Crescas, Maimonides, Averroes, Spinoza, the Kalam, the Church Fathers, and the foundations of Western religion. His greatest contribution may therefore have been in collapsing all the artificial barriers that isolated the study of Christian philosophy from Islamic philosophy from Jewish philosophy (Twersky 1975). Being the first Judaica scholar to progress through an entire career at a top-tier university (Mendes-Flohr 1998), in Wolfson is also represented the fulfillment of the goals of the 19th-century Wissenschaft des Judentums movement.
Wolfson was born to Sarah and Max Wolfson in Astryna (Yiddish: Ostrin), Vilna Governorate (in present-day Shchuchyn district, Grodno Region, Belarus), and in his youth he studied at the Slabodka yeshiva under Rabbi Moshe Mordechai Epstein. He emigrated to the U.S. with his family in 1903. In September 1908, Wolfson arrived in Cambridge, Massachusetts and earned his bachelor's degree and Ph.D. from Harvard University, where he remained for the rest of his career, excepting the years 1912–1914, when he held a traveling fellowship from Harvard which enabled him to study and do research in Europe, and some months in 1918 when he was conscripted into the Army, and together with Norbert Wiener received basic training at Fort Slocum, New York, and was then transferred to the Adjutant General's Office in Washington, D.C.. R.D. Crouse, the scholar of early medieval theology, was among his students.
