Frary was a professor at Yale. He specialized in international affairs. During his tenure at Yale Frary completed two books that established him as one of the pre-eminent scholars on the subject of
Eastern Europe. His third book, "How the World Votes," co-authored with fellow Yale professor
Charles Seymour, garnered considerably more critical praise, so much so that nearly a century later it is still considered one of the best books on the
electoral process. He was appointed as an aide in the
United States Department of State. He was chosen as a member of the
Paris Peace Conference, 1919 by President
Woodrow Wilson due to his knowledge of events in
Bulgaria. He served as secretary to Colonel
Edward M. House during the conference. ==Personal life==
