George G. Fleming, 68, a retired insurance company executive and former Washington resident who had been active in civic affairs, died of cancer June 18 in a hospital in Ocala, Fla.

Mr. Fleming came to Washington in 1949 with the Progressive Life Insurance Co. During the 1950s, he served on the city's Public Welfare Advisory Council. In the early 1960s, he was president of the Negro Community Council of the National Capital Area.

He also had served on the board of directors of the Urban League, as vice chairman of the National Council of Christians and Jews and vice president of the Washington Community Chest.

Mr. Fleming moved to New Jersey in 1963. He became a vice president and member of the board of directors of Progressive Life. He retired to Ocala about three years ago.

He was active in Republican Party politics in New Jersey. As an alternate delegate to the GOP national convention in 1964, Mr. Fleming opposed the nomination of Sen. Barry Goldwater (R-Ariz.) as the party's standard-bearer.

Following Goldwater's nomination, Mr. Fleming became president of the National Negro Republican Assembly, a group which worked for the election of local and state Republican candidates. The assembly opposed the civil rights program of the national party and did not endorse a presidential candidate in 1964.

Mr. Fleming later was elected to the executive board of the New Jersey State Central Committee.

He was born in Jacksonville, Fla., and reared in Asbury Park, N.J. He joined the Progressive Life Insurance Company in 1937 as a subagent, and came to Washington to open company territories in Maryland, Virginia, and the District.

Survivors include his wife, Katherine, of Ocala; a daughter, LaVerne Guines of Washington, and a brother, Frank, also of Washington.
