William Armstrong Percy III (December 10, 1933 – October 30, 2022) was an American professor, historian, encyclopedist, and gay activist. He taught from 1968 at the University of Massachusetts Boston, and started publishing in gay studies in 1985. Early life and education Bill was born to Anne Minor Dent and William Armstrong Percy, II, of the Mississippi Percy family. His mother was raised by her widowed uncle, the distinguished Memphis lawyer Dent Minor. He was a descendant of 17th-century Dent settlers in Maryland and the Minors in Virginia. Dent's great-uncle John B. Minor taught law at the University of Virginia from 1845 to 1895 and served for decades there as dean of the Law School. After graduating as valedictorian of Middlesex School (in Concord, Massachusetts) in 1951, Percy went to Princeton University, where he entered the Special Program in the Humanities. There, he struggled with the rejection and persecution of gays during the McCarthy years. At a time when conscription was still in effect, he volunteered for the U.S. Army. In his military stint, Percy studied Norwegian at the Army Language School Monterey, Ca. He worked as a French interpreter on loan to the Central Intelligence Agency on the island of Saipan. Career Percy taught at the University of New Orleans, Louisiana State University, and the University of Missouri at St. Louis for two years each. In 1968 he moved to the University of Massachusetts at Boston. After gaining tenure and promotion to full professor there, in 1975 Percy "came out" to colleagues. He joined the fight for equal rights for gays in 1982 after meeting gay activist Charley Shively. Three years later, Percy began publishing articles on homosexuality, including in the very radical Gay Community News, based in the South End of Boston. Soon after, Percy served as the other associate editor with Warren Johansson of the Encyclopedia of Homosexuality (1990), which won six prizes. It has recently been reprinted by Rutledge, costing $500 for the two volumes. Paul Cartledge, of the University of Cambridge, described Percy's Pederasty and Pedagogy in Archaic Greece (1996) as the first work to try to go beyond Kenneth Dover's "groundbreaking" Greek Homosexuality. Dover's work, influenced by pseudo-Freudianism, was very homophobic. Cartledge noted there were finer works in German that were translated into English before Dover wrote. At the time Percy published Outing: Shattering the Conspiracy of Silence (1994), co-authored with Warren Johansson, he
