In 1916 he became associate editor of the Geographical Review. He was associate editor of the Journal of Geography in 1918−19 and editor in 1919−20. In 1921 he became a director of the newly formed Council of Foreign Relations. Bowman served as President of Johns Hopkins University in Baltimore, Maryland from 1935 to 1948 and President of the History of Science Society in 1944. Bowman was also a know anti-semite, extremely suspect of Jews and reluctant to hire them at the university. According to Neil Smith's "American Empire: Roosevelt's Geographer and the Prelude to Globalization" (University of California Press, 2004), Bowman fired one of the most promising young historians on the Johns Hopkins faculty in 1939, saying "there are already too many Jews at Hopkins." In American Empire, Bowman is further quoted as saying "Jews don't come to Hopkins to make the world better or anything like that. They come for two things: to make money and to marry a non- Jewish woman." In 1942, Bowman he instituted a quota on the admission of Jewish students.
Beginning in 2005, the American Geographical Society has helped launch international collaborative research projects, called the Bowman Expeditions in Bowman's honor, in part to advise the U.S. government concerning future trends in the humanterrain of other countries. The first project, in Mexico, is called Mexico Indigena, and has generated considerable controversy, including a public statement from the Union of Organizations of the Sierra Juarez of Oaxaca (UNOSJO) denouncing Mexico Indigena's lack of full disclosure regarding funding procured from the DOD, via the U.S. Army's Foreign Military Services Office, Ft. Leavenworth, Kansas.
