Anton Charles Pegis (August 24, 1905 – May 13, 1978) was an American philosopher and historian of philosophy in the tradition of Thomas Aquinas.
Pegis was the earliest of what would become a prominent group of historians of medieval philosophy, including Joseph Owens and Armand Maurer, who studied under Étienne Gilson and spent the majority of their careers teaching at the Pontifical Institute of Mediaeval Studies.
[2] In the fall of 1928, while a scholarship student at University of Chicago, Pegis took inspiration from the lectures of Carl Darling Buck and Paul Shorey.
[3] Pegis left the Pontifical Institute of Mediaeval Studies in 1952 to assume the editorial directorship of Doubleday's Catholic textbook division.
[4] Pegis, along with Gilson, was a firm advocate of Pope Leo XIII's Aeterni Patris and its exhortation to a revival of Thomism.
