According to Ruppelt: "Father Hayden (sic) was head of the astronomy department at Georgetown University. I never met him but Dr. Steve Possony was always going to him with our UFO problems. Father Hayden (sic) seemed to be very much interested in our problems and couldn't at all be classed as a scoffer." Ruppelt has misspelled the last name, which is Heyden. Father Heyden (1907-1991) came to Georgetown in 1945 from the Manila Observatory in the Philippines and was awarded for outstanding accomplishments and contributions to the popularization or advancement of the science of astronomy there. In 1948 he assumed directorship of the Georgetown Observatory. He was awarded as a Regular Member of the Society for Imaging Science and Technology for outstanding achievement in imaging science or engineering in 1967. Besides his keen interest in UFOs, he also studied the famous Piri Reis ancient maps. He knew astronomer Clyde W. Tombaugh and his famous UFO observation.
