In 1959, as part of his doctorate studies, Pryor went to Berlin, where he was finishing his doctoral thesis and also taking classes at the Free University of West Berlin. In August 1961, days after the Berlin Wall was erected, he visited East Berlin to deliver a copy of his dissertation to a professor there, and to contact a friend's sister, an engineer who – unknown to Pryor – had just illegally fled to West Germany. The Stasi arrested Pryor on charges of aiding the woman's escape; after the police found a copy of Pryor's doctoral dissertation, he was accused of espionage and detained without charge. Pryor's cell was directly above an East German torture room. While jailed, Pryor was intensively interrogated, although not tortured. On February 10, 1962, after almost six months of detention, Pryor was freed at Checkpoint Charlie, just before American U-2 pilot Francis Gary Powers was swapped for Soviet KGB Colonel William August Fisher at the Glienicke Bridge between West Berlin and Potsdam, East Germany, as a result of negotiations conducted by James B. Donovan. Pryor's involvement in this incident is dramatized as a subplot in the 2015 film Bridge of Spies starring Tom Hanks as Donovan. Actor Will Rogers depicted Pryor. Pryor was not consulted for the film, about which he commented, "It was good. But they took a lot of liberties with it."
Career
Pryor received his doctorate from Yale in 1962, but his purported involvement in espionage and his imprisonment limited job opportunities in government—his preferred career—or industry. Pryor did not want to teach but went to work in academia, as an economics instructor at the University of Michigan until 1964 and as a staff research economist at Yale until 1967. He joined the economics faculty at Swarthmore College in 1967; "Swarthmore didn’t care" about his imprisonment, Pryor recalled. "In fact, I think the students kind of got a kick out of having an ex-con teaching them". He became a full professor, and chaired the department for three periods in the 1980s. Pryor specialized in comparative economics; he retired from active work at the college in 1998, but remained a professor emeritus. Pryor published 13 books and more than 130 scholarly articles. Pryor worked as an economic advisor in Ukraine and Latvia, was employed as a consultant to the World Bank in Africa, served as a Research Director to the Pennsylvania Tax Commission, and was a research associate at both the Hoover Institution in Palo Alto, California, and the Brookings Institution in Washington, D.C. He twice served as judge of elections, a local elected position in Pennsylvania. He won research grants from the National Science Foundation, the National Council of Soviet and East European Studies, and the Carnegie Endowment for International Peace. He served as a trustee at historically black colleges such as Miles College, Wilberforce University, and Tougaloo College.
Personal life
On March 26, 1964, Pryor married Zora Prochazka, who was also an economist. They remained together until her death in 2008. Pryor died on September 2, 2019, in Newtown Square, Pennsylvania, where he had lived the final 11 years of his life.
