The following year, he became a liaison officer in the Caribbean office of the Lend-Lease program. He then joined the State Department, where he became assistant chief in the division of research for the American Republics and then assistant to the chief of the historical division.

He returned to the University of Maryland in 1956 and remained there until 1959, when he joined the faculty at the University of California at Santa Barbara.
