Retired Marine Corps Brig. Gen. Joseph H. Fellows, 82, a decorated veteran of both world wars, died of pneumonia Tuesday at the Veterans Administration Hospital in Martinsburg, W. Va.

Gen. Fellows was serving at Marine Headquarters in Washington at the outbreak of World War II. He was soon assigned to the staff of Adm. William Halsey in the Pacific and then, from November 1943 until the end of the war, served as a logistics officer on the staff of Fleet Adm. Chester W. Nimitz.

Gen. Fellows was one of those Allied officers present aboard the battleship Missouri on Sept. 2, 1945, when Japanese representatives signed the instrument of surrender, which ended the war.

A native of Washington, Gen. Fellows was a graduate of the old Western High School where he commanded the corps of cadets.

He received his commission shortly after joining the Marine Corps in World War I. He served with the 5th Marine Regiment in battle of Belleau Wood in France.

Between the wars he served in campaigns in Santo Domingo and Nicaragua, and served aboard ships of the Pacific Fleet. He had attended George Washington University and was a graduate of the Armed Forces Industrial College and the Naval War College.

His medals included the Legion of Merit, the Bronze Star, and the Purple Heart.

Following his retirement from active duty in 1949, Gen. Fellows moved to Upperville, Va., where he farmed until retiring a second time in the early 1960s.

Survivors include his wife, Lillian, and a daughter, Dorthy F. Bauer, both of Upperville, and two grandchildren.
