In 1946–47, Dr. Hopper served on the site selection board for the new
United States Air Force Academy. Upon his return to academia in 1947, he found himself passed over for promotion above associate professor. The classified nature of most of Hopper's research output did not help his prospects, as well as the extended time he spent away from academia with the military, two years more than most of his colleagues. Post war he shifted his teaching interests more towards air power as a factor in international affairs and did not become significantly involved in the new Russian Research Center, known today as the Davis Center for Russian and Eurasian Studies. In the 1940s and 1950s, Dr. Hopper was a frequent speaker at the
Naval War College and
Army War College on Soviet/Russian affairs. He also traveled extensively, performing speaking tours across Europe and Central America. He was a Trustee of the World Peace Foundation and held membership in the Institute of Pacific Relations, the American-Russian Institute, the Council of the Foreign Policy Association, and the
Council on Foreign Relations. After retiring from Harvard in 1961, Dr. Hopper lived in Santa Barbara, California. Shortly before his death he wrote that he was "grateful to Harvard beyond measurement". He added, "Of all the privileges granted to me, I cared most about teaching, especially on my return from World War II". He concluded, "I miss the classroom where it is always morning, and night can never come". Hopper died on July 6, 1973. His papers are divided between the Library of Congress, the University of Montana, and the University of California, Santa Barbara. == References ==
