In the fall semester of 1964 I took two graduate seminars at Berkeley in the subfields of American history I was then considering as a specialty. One was in diplomatic history, taught by Visiting Professor Gerald Wheeler. He was substituting for the Department’s on-leave Armin Rappoport, whose two-semester lecture course I had taken the year before as a first-year grad student. The other was Robert Middlekauff’s seminar in colonial history, or as we would say now, British North America. That seminar was largely intellectual history simply because much of it was devoted to the works of Perry Miller. Reading Miller and participating in Middlekauff-led discussions made it clear to me that intellectual history was the path I wanted to take.
