Frederic Pryor

Frederic LeRoy Pryor (April 23, 1933 – September 2, 2019) was an American economist. While studying in Berlin during the partition of the city in 1961, he was imprisoned in East Germany for six months, then released in a Cold War "spy swap" that also involved downed American U-2 pilot Francis Gary Powers and Soviet intelligence officer Rudolf Abel. He spent the bulk of his career as a member of the Swarthmore College faculty, as a professor of economics. Provided by Wikipedia
