Nolan Bailey Harmon was born July 14, 1892, in Meridian, Mississippi, and died on June 8, 1993, living to be over 100 years old. His funeral was held on June 12, 1993, at Druid Hills United Methodist Church, and he was buried in the Evergreen Burial Park in Roanoke, Virginia. He was the son, grandson and great-grandson of Methodist Preachers. He was elected a bishop of The Methodist Church and United Methodist Church in 1956. Harmon's wife Rebecca Lamar died at age 84 in 1980. His children were Nolan B. Harmon III and G. Lamar Harmon.
In 1940, Harmon was elected book editor of the newly reunited Methodist Church. He edited publications of Abingdon Press and the journalReligion in Life. He also was general editor of the twelve volume Interpreters Bible. Between 1960 and 1964, Bishop Harmon was a member of The HymnalCommittee of his denomination, serving as chairman of the Subcommittee on Texts. He was elected by the Southeastern Jurisdiction Conference of The Methodist Church. As a bishop, he presided over the work of various Annual Conferences in the Southeastern United States. He retired from the active episcopacy in 1964. In retirement he edited the Encyclopedia of World Methodism. Also in retirement, Bishop Harmon served on the faculty of Emory University as a visiting professor, continuing there into his 96th year. Further into his retirement, Nolan taught classes on government and history of Methodists. A friend of his drove him to and from classes, and he lived by the university at the time.
In April 1963, Bishop Harmon made civil rights history when he, along with seven other white clergymen, released a statement calling on African Americans to stop taking part in demonstrations initiated by the Rev. Dr. Martin Luther King Jr.. The statement, titled "A Call for Unity," called the demonstrations "unwise and untimely," and argued that change should be pursued through negotiation and judicial action. This statement motivated Dr. King to write his famous "Letter from Birmingham Jail." In his 1983 autobiography, Bishop Harmon referred to the letter as a "propaganda move," but also wrote that he "certainly gave his due as a brave man fighting off ages of evil." In June 1963, Bishop Harmon spoke out after segregationist Governor George Wallace attempted to block the enrollment of black students at the University of Alabama, also known as the "Stand in the Schoolhouse Door." Bishop Harmon read a public protest of Wallace's actions during an Annual Conference, calling them a "moral mistake" and adding that "the sovereignty of the United States has been exerted to see that fundamental human rights are maintained in our state universities and state schools." His words were published in local newspapers. Bishop Harmon died June 1993, the first U.M. Bishop to live to be 100 or more since Bishop Herbert George Welch. He was also the oldest out of the eight white clergymen.
