He taught European history at Williams College as assistant and then associate professor.  In 1936 he became Dean of Students at Williams College.  He was also a trustee of Vassar College.  He then entered a career in government service.  During World War Two, he served in the Office of Strategic Services.  In 1947, he was assistant military attaché at the U.S. Embassy in Paris.  In 1948-1949 he worked for the Brookings Institution.  He later served as a reserve foreign service officer in Paris and at the U.S. Embassy in Stockholm.  According to obituaries, however, he actually worked for the Central Intelligence Agency from 1949 to 1962.  Birdsall died at the age of seventy in Christiansted, United States Virgin Islands, where he had been in retirement for eight years. Hans Wilhelm Gatzke (1915–1987) was a historian of German foreign policy since World War I.  Born in Dülken, Germany, he attended the University of Bonn and the University of Munich, finally graduating from Williams College in 1938.  After serving in the United States Army during World War II as a second lieutenant, he received his M.A. (1939) and PhD.  (1947) from Harvard University.  He taught at Johns Hopkins University from 1947 to 1964, during which time he was awarded a Guggenheim Fellowship in 1956.  He joined the department of history at Yale University in 1965 and remained there until his retirement in 1986.  Gatzke anonymously funded a prize, awarded biennially by the American Historical Association, in honor of Paul M. Birdsall (who was Dean of Students at Williams when Gatzke arrived there in the late 1930s) for the best work in the field of European military or strategic history since 1870.  His involvement was revealed upon his death in 1987.  He is remembered by a named professorship in his honor (the Hans W. Gatzke '38 Professor of Modern European History) at Williams College.

Williams College is a private liberal arts college in Williamstown, Massachusetts, United States.  It was established in 1793 with funds from the estate of Ephraim Williams a colonist from the Province of Massachusetts Bay who was killed in the French and Indian War in 1755.  The college was ranked first in 2017 in the "U.S. News & World Report"' s liberal arts ranking for the 15th consecutive year, and third among liberal art colleges in the 2017 "Forbes" magazine ranking of America's Top Colleges. Mark C. Taylor (born 13 December 1945) is a philosopher of religion and cultural critic who has published more than twenty books on theology, philosophy, art and architecture, media, technology, economics, and the natural sciences.  After graduating from Wesleyan University in 1968, he received his doctorate in the study of religion from Harvard University and began teaching at Williams College in 1973.  In 2007, Taylor moved from Williams College to Columbia University, where he chaired the Department of Religion until 2015. Edward Everett Wilson was an African-American lawyer born in Texas, on January 1, 1867.  He initially attended Oberlin College, but later transferred to Williams College.  He received his degree, with honors, from Williams College in 1892.  Wilson was elected to the Phi Beta Kappa honorary society, one of the first African Americans to attain that honor.  Subsequently, he obtained his Bachelor of Laws degree from Howard University in 1894.  Moving to Chicago, he filled the post of assistant state attorney for Cook County, Illinois, from 1912 until his retirement in 1947.  Wilson died in France while on vacation on February 21, 1952. Brian Lukacher is professor of art at Vassar College where he has taught since 1986.  Lukacher received his M.A. from Williams College, and received his PhD from the University of Delaware.  Following his time at Williams College, Lukacher received the Chester A. Dale and Samuel H. Kress Fellowship for 1981 at the National Gallery of Art, Washington, D.C. His research interests relate to the social history and esthetic philosophy of late eighteenth and nineteenth-century British art and architecture.  Lukacher completed his PhD on the architecture of Joseph Gandy about which he subsequently produced a monograph that was published by Thames & Hudson in 2002.  In 2001 he gave the annual Soane Lecture on Joseph Gandy. Zephaniah Swift Moore (November 20, 1770 – June 29, 1823) was an American Congregational clergyman and educator.  He taught at Dartmouth College during the early 1810s and had a house built in Hanover, New Hampshire that now serves as Dartmouth's Blunt Alumni Center.  He served as the President of Williams College between 1815 and 1821 and the first President of Amherst College between 1821 and 1823.  He is most famous for abandoning Williams in order to found Amherst, taking some of the faculty and 15 students with him.  Supposedly, he also took portions of the Williams College library with him.  Though plausible, this account is unsubstantiated, and was declared false in 1995 by Williams College President Harry C. Payne.  Moore died two years after Amherst was founded, and was succeeded by Heman Humphrey, a trustee of Williams College.  His departure from Williams established the foundation for the intense Williams-Amherst rivalry that persists to the present.  To this day, he is regarded with a measure of derision on the Williams campus. Frank J. "Buck" O'Neill (March 6, 1875 – April 21, 1958) was an American football player and coach.

O’Neill was a two-sport athlete at Williams College where he played football and ran track.  He was inducted into the College Football Hall of Fame as a coach in 1951.
