Langdon Brown Gilkey (February 9, 1919 – November 19, 2004) was an American Protestant ecumenical theologian.

Early life and education

A grandson of Clarence Talmadge Brown, the first Protestant minister to gather a congregation in Salt Lake City, Gilkey grew up in Hyde Park, Chicago. His father Charles Whitney Gilkey was a liberal theologian and the first Dean of the University of Chicago's Rockefeller Chapel; his mother was Geraldine Gunsaulus Brown who was a well known feminist and leader of the YWCA.

Gilkey attended elementary school at the University of Chicago Laboratory School, and in 1936 graduated from the Asheville School for Boys in North Carolina. In 1940, he earned a Bachelor of Arts in philosophy, magna cum laude, from Harvard University, where he lived in Grays Hall during his freshman year. The following year, he went to China to teach English at Yenching University and was subsequently (1943) imprisoned by the Japanese, first under house arrest at the university and later at Weixian Internment Camp near the city of Weifang in Shandong Province (where Eric Liddell was a fellow internee).

Career

After the war, Gilkey obtained his doctorate in religion from Columbia University in New York, being both mentored by and a teaching assistant to Reinhold Niebuhr. He was a Fulbright scholar at Cambridge University (1950–51), and went on to become a professor at Vassar College from 1951 to 1954, and then at Vanderbilt Divinity School from 1954 to 1963. He received a Guggenheim Fellowship in 1960 to study in Munich; another Guggenheim in the mid-1970s took him to Rome. In late 1963 he became a professor at the University of Chicago Divinity School, eventually being named Shailer Mathews Professor of Theology, until his retirement in March 1989. While on sabbatical in 1970, he taught at the University of Utrecht in the Netherlands; in 1975 he taught at Kyoto University in Japan, his lecture series there focusing on the environmental perils of industrialization. After his retirement he continued to lecture until 2001 at both the University of Virginia and Georgetown University. but was popularly known for his writings on science and religion.

His early books and articles demonstrated the existential power of his experiences, from his early pacifist professions as a student at Harvard University, where his classmates included, among others, future President John F. Kennedy, Pete Seeger, and Cardinal Avery Dulles, to his teaching in China and his experiences as a POW.

His teachers, especially Niebuhr and Tillich, at Union Theological Seminary, helped him with methods and categories to formulate a powerful and creative theological vision of his own. In the 1970s and 1980s, Gilkey's theological vision was colored by the growth of Buddhism, and Sikhism as both religions began to influence religious life in America. He held the view most world religions enjoyed "rough parity". "The question for our age," he once wrote, "may well become, not will religion survive, as much as will we survive and with what sort of religion, a creative or demonic one?"
