William Hawley Clark (May 10, 1919 – March 7, 1997) was bishop of the Episcopal Diocese of Delaware, serving as diocesan from 1975 to 1985.
The onset of World War II held up his plans to study for his junior year abroad at the American University in Beirut.
On June 12, 1943, Clark married Rosemary Ellen Lehman of Fort Wayne, Indiana at St Andrew's Episcopal Church in Ann Arbor, Michigan.
During his time there he taught at Episcopal Theological School, served on the standing committee of the diocese, and oversaw plans to expand Trinity in Concord by the building of a new church next to the older one.
After one more year at Trinity, Concord, he joined the staff of the World Council of Churches in Geneva, Switzerland in 1962.
[1] On January 24, 1975, he was elected diocesan bishop by a convention held at St David's Church in Wilmington, Delaware.
He continued his work in the areas of ecumenical relations, affirming women to become priests and bishops, and ensuring that the diocese cared for the needs of the people of Delaware and the wider world.
His funeral was held March 11, 1997 at the Cathedral Church of St John in Wilmington, with his successor, Rt Rev Cabell Tennis as preacher.
