Donald E. Gibson spent more than 30 years as professor of sociology at the University of Pittsburgh at Greensburg.  An impressively wide-ranging scholar of social issues, he is also author of two books (and several articles published in Probe) on Kennedy: Battling Wall Street (1994/2014), which challenges conventional wisdom to assert that Kennedy was always on the side of economic, political, and social progress; and The Kennedy Assassination Cover-Up (1999), on the Warren Commission's connection to the Eastern Establishment.  See further here.
