Olin L. Stubbs, 66, who retired in 1977 as assistant director of the convention office at American Red Cross headquarters here, died of cancer Saturday at Alexandria Hospital. He lived in Alexandria.

Mr. Stubbs joined the convention office in 1971 and oversaw the planning and arrangements for the national organization's annual meetings at such places as Miami, Boston and Portland, Ore.

He became a member of the Red Cross staff here in 1953, when he was named assistant field director in the office of services at military installations. Later, he was assigned to Weisbaden, Germany, as a field director. He saw special duty at Naples, Italy, during the 1956 Suez Canal crisis and at Bremerhaven, Germany, where he supervised the sea transportation of Hungarian refugees after the 1956 revolt.

Before returning here in 1963, Mr. Stubbs was a field director for the Pacific side of the Panama Canal Zone. He was a senior buyer with the Red Cross national supply office in Alexandria until joining the convention office.

Mr. Stubbs was born in Sumter, S.C., and grew up in Norfolk, Va. He attended Catholic University.

During World War II, he served with the Army Corps of Engineers in Europe. After the war, he became a civilian employe of the corps at Fort Belvoir.

Survivors include his wife, Margaret W., of Alexandria; a daughter, Jane B. Stubbs-Dixon of San Francisco; a brother, Jack B., of Houston, Tex., and two sisters, Mary Louise James of Raleigh, N. C., and Dallas McGlynn of Silver Spring.

The family suggest that expression of sympathy be in the form of contributions to the Olin L. Stubbs Memorial Fund, American Red Cross.
