In 1964, DuBay struck up a friendship with George J. Gessner, a United States soldier who was incarcerated at Leavenworth, Kansas after being accused of disclosing nuclear weapons secrets to Soviet officials. Gessner, who had taken an interest in DuBay's progressive outlook and struggle with the Catholic establishment, exchanged letters with the priest between 1964 and 1966 about the Bible and race, church reform, philosophy, literature, and current events. The file includes letters that were mailed by Gessner to DuBay, as well as several article clippings pertinent to their discussions.
