Retired Navy Capt. Samuel Pemberton Moncure, 68, a veteran of World War II and the Korean conflict, died Monday at Alexandria Hospital after a stroke.

His last assignment was in the office of the chief of naval operations before he retired at the end of 1961. He then was vice president in charge of public relations at the United Virginia Bank in Alexandria until retiring for a second time in 1975.

Born in Fredericksburg, Va., Capt. Moncure grew up in ALexandria. He graduated in 1932 from the Naval Academy in Annapolis, where he was an All-American lacrosse player and played football.

In World War II, he was aboard the battleship USS Alabama in the Pacific and the cruiser USS St. Paul. In the Korean conflict, he commanded destroyers and then the heavy cruiser USS Des Moines, flagship of the 6th Fleet in the Mediterranean.

Capt. Moncure took part in many civic activies in Alexandria. He was on the board of the Northern Virginia Branch of the Washington Urban League. He was active in the Salvation Army, United Givers Campaign, and the American Red Cross.

He was a past president of the Alexandria Rotary Club, vestryman of Immanuel Church-on-the-Hill and a former trustee of Episcopal High School.

He is survived by his wife, Jane Belt Moncure, of the home in Alexandria; two daughters, Mrs. Jeremy R. Taylor, of Alexandria, and Marion Moncure, of Breckenridge, Colo.; a son, Samuel P. Jr., of Phoenix, Ariz.; a sister, Mrs. Gardner L. Booth II, and a brother, William A., both of Alexandria; another brother, Richard W., of Lookout Mountain, Tenn., and two grandchildren.

The family suggests that expressions of sympathy may be in the form of contributions to Episcopal High School or the Salvation Army of Alexandria.
