Why was my father teaching contemporary religion when he was a professor of engineering? Well, he spent a year on a fellowship at the Pacific School of Religion in Berkeley - the grant was to allow people in the sciences to study any aspect of religion they liked. My dad got into Kierkegaard in a big way. He then went on to earn his Ph.D. in structural engineering at Virginia Tech, and landed a job at Bucknell University right out of grad school. Hence the Lewisburg, PA location.
"Atom bomb spy" and Communist Morton Sobel became a longtime family friend because of Dad's prison work. Helen Sobel used to stay with us when she'd travel by bus from New York City to visit Morton. In later years, when Morton was out of jail and we would visit them in New York, I was disappointed by his answers to my political questions. Communism didn't sound so great to my 14-year-old mind. And my brother never got a straight answer to the question: "Did you do it?" (i.e. pass secrets to the Russians). Doesn't change my feeling that the Rosenbergs were electrocuted for political reasons.
Jimmy Hoffa only attended Dad's class once. Guess he didn't think Kierkegaard was The Man.
