John Boswell

The Marriage of Likeness: Same-Sex Unions in Pre-Modern Europe (New York: Villard, 1994) argues that the adelphopoiia liturgy was evidence that the attitude of the Christian church towards homosexuality has changed over time, and that early Christians did on occasion accept same-sex relationships.

Boswell died of complications from AIDS in the Yale infirmary in New Haven, Connecticut, on December 24, 1994, aged 47.

The Kindness of Strangers: Child Abandonment in Western Europe from Late Antiquity to the Renaissance (1988) is a scholarly study of the widespread practice of abandoning unwanted children and the means by which society tries to care for them. The title, as Boswell states in the Introduction, is inspired by a puzzling phrase Boswell had found in a number of documents: aliena misericordia, which might at first seem to mean "a strange kindness", is better translated "the kindness of strangers," echoing the line "I have always depended on the kindness of strangers" from A Streetcar Named Desire by Tennessee Williams.

Christianity, Social Tolerance, and Homosexuality (1980) is a work which, according to George Chauncey et al. (1989), "offered a revolutionary interpretation of the Western tradition, arguing that the Roman Catholic Church had not condemned gay people throughout its history, but rather, at least until the twelfth century, had alternately evinced no special concern about homosexuality or actually celebrated love between men." The book won a National Book Award and the Stonewall Book Award in 1981, but Boswell's thesis was criticized by Warren Johansson, Wayne R. Dynes, and John Lauritsen, who believed that he had attempted to whitewash the historic crimes of the Christian Church against gay men.

His first book, The Royal Treasure: Muslim Communities Under the Crown of Aragon in the Fourteenth Century, appeared in 1977. In 1994, Boswell's fourth book, Same-Sex Unions in Pre-Modern Europe, was published. He died that same year from AIDS-related complications.

The Royal Treasure (1977) is a detailed historical study of the Mudéjar Muslims in Aragon in the 14th century.

A medieval philologist, Boswell spoke or read several Scandinavian languages, Old Icelandic, German, French, Spanish, Italian, Latin, Greek, early and modern Russian, Old Church Slavonic, Armenian, Persian, Arabic, Hebrew, Syriac, and Akkadian. Boswell received his doctorate 1975 and joined the Yale University history faculty, where his colleagues included John Morton Blum, David Brion Davis, Jaroslav Pelikan, Peter Gay, Hanna Holborn Gray, Michael Howard, Donald Kagan, Howard R. Lamar, Jonathan Spence, Robin Winks, William Cronon, and Edmund Morgan. Boswell was made full professor in 1982, and A. Whitney Griswold Professor of History in 1990.

John Eastburn Boswell (March 20, 1947 – December 24, 1994) was an American historian and a full professor at Yale University. Many of Boswell's studies focused on the issue of religion and homosexuality, specifically Christianity and homosexuality. All of his work focused on the history of those at the margins of society.

Boswell was born on March 20, 1947, in Boston, Massachusetts, the son of Colonel Henry Boswell Jr. and Catharine Eastburn Boswell. He earned his AB at the College of William & Mary, and his PhD at Harvard University before being hired to teach at Yale University.
