John W. DuBose, 96, a retired lieutenant commander in the Navy and a former real estate agent in Washington died of bronchial pneumonia Friday at the Wisconsin Avenue Nursing Home.

Cmdr. DuBose, who was born in Gadsden, Ala., graduated from the U.S. Naval Academy at Annapolis in 1908. His early Navy career included service aboard the old battleship North Carolina. In 1915, he retired for reasons of health.

During World War I, he went back on active duty and served until the early 1920s, when he moved to Washington and became a real estate agent. During World War II, he again was called to active duty. He was a member of the general court martial board at the Washington Navy Yard when he retired in 1946. Although he did some real estate work, he was substantially in retirement for the rest of his life.

Cdr. DuBose was a Knight of the Golden Circle of the Army & Navy Club in Washington and a member of the Kenwood Golf and Country Club and the Naval Academy Alumni Association.

Survivors include his wife, Estelle T., of Washington; one son, John W., Jr., of Spotsylvania, Va.; one daughter, Mrs. Albert A. Thompson Jr. of Cupertino, Calif.; seven grandchildren, and two great-grandchildren.
