Stuart A. Bingham, 75, a retired government employe with 36 years of service, died of cancer Saturday at Georgetown University Hospital.

Mr. Bingham was born in New York City, educated in Indiana, attended the University of Pennsylvania, and then moved to Butte, Mont. He began his government career in 1933 with the Reconstruction Finance Corp., with responsibility for the agency's operations in Montana.

He became a lieutenant colonel in the Army during World War II and was part of the military government of Osaka, Japan, when the war was over. He moved to the Washington headquarters of the RFC about 1947 and remained with it until RFC was disbanded in 1952.

He later joined the Small Business Administration as chief of its loan division. About 1960, he transferred to the Department of the Aif Force as a commercial loan specialist in the office of the comptroller. He retired in 1969.

Mr. Bingham was a member of the Kena Shire Temple in Alexandria. He had lived in Alexandria for many years until 1977, when he moved to Rossmoor Leisure World in Silver Spring.

Survivors include his wife, Helen E., of the home; two step-daughters, Connie L. Gramm, of Vienna, and Carol L. Harreld, of the District of Columbia; a sister, Mrs. J. Morgan Glover, of Tuxedo Park, N.Y., and five grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Shriners Hospital for Crippled Children, 8400 Roosevelt Blvd., Philadelphia, Pa., of to the Vincent T. Lombardi Cancer Research Center, Georgetown University Hospital, Washington.
