The Rev. Charles Sumner Pryor, 94, pastor of the Alexander Memorial Church in Georgetown for 30 years before retiring as pastor emeritus in 1972, died Friday at the Wisconsin Avenue Nursing Home after a stroke.

Mr. Pryor was born in Dallas and lived in Fredericksburg, Va., before arriving in Georgetown by river barge at the turn of the century. His father, the Rev. Charles Nelson Pryor, was a minister in Georgetown before him.

Mr. Pryor graduated from Armstrong High School and worked as a government clerk and band leader before entering the ministry. He told a Post reporter in a 1968 interview that on Christmas Day in 1928, his father gave him a Bible, and that he had the feeling that his father "was handing his mantle" over to him.

The younger Mr. Pryor, who had been a church organist, Sunday school superintendent, and secretary of the trustee board of the Alexander Church, was elected pastor in late 1941. He had graduated from the Washington Baptist Theological Seminary in 1937 and was ordained two years later.

During his years as pastor, he became known for his memory, his joy in conducting weddings and baptisms, and for the nickname, "Uncle Charlie." The ministry had its harder moments as well. In March 1968, he and Walter Fauntroy eulogized a District policeman, Eugene I. Williams, who was shot to death while on duty and was a member of the Alexander Church:

Mr. Pryor told how the officer had gone to Sunday school at the church and how "at the age of 15 he became a Christian . . . I baptized him right where I'm standing. He was courageous, studious and didn't have too much foolishness. He loved his church. He loved his pastor . . . We don't understand why things like this happen."

In addition to his post as pastor, he had been recording secretary of the Mount Bethel Baptist Association and was pianist and organist for the Baptist Convention and the Baptist Ministers Conference here. Following his retirement as pastor, Mr. Pryor taught music at the Baptist Seminary.

His wife of 35 years, the former Mary Anderson Basie, died in 1955. Mr. Pryor leaves no immediate survivors.
