Harry Clinton Breeden Sr., 91, a former U.S. Deputy Marshal and a retired streetcar operator who served in Europe during World War I, died of bronchial pneumonia Saturday at the Veterans Administration Hospital here.

Mr. Breeden lived in Washington for 66 years before moving to Gaithersburg two years ago.

Born in Aden, Va., he worked his family's retail furniture business in Remington, Va. before moving here in 1912.

During World War I, he served with a 312th machine gun battalion with the American Expeditionary Forces in France. He was wounded and was awarded the Purple Heart with oak leaf cluster.

After the war, Mr. Breeden returned here and worked as a personal bodyguard for Washington Socialite Evelyn Walsh McLean. He then served as a deputy marshal for the District Court for about four years before joining the old Capital Transit Co. as a streetcar operator in 1932. He retired in 1955.

Mr. Breeden was a past commander of American Legion Post No. 46 and a member of St. Luke's United Methodist Church here for many years.

Survivors include his wife of 56 years, Ethel T., of Gaithersburg; two sons, Harry C. Jr., of Fort Lauderdale, Fla., and Townsend D., of Boyds, Md., and two grandsons.

The family suggests that expressions of sympathy be in the form of contributions to St. Luke's United Methodist Church in Washington.
