Retired Rear Adm. Allan S. Chrisman, 71, former deputy surgeon general and assistant chief of the Bureau of Medicine and Surgery of the Navy Department, died Tuesday at Potomac Valley Nursing Home in Rockville after a series of strokes.

He had first served at the bureau from 1952 to 1956. He then was commanding officer of the Naval Hospital at San Diego, Calif., returning to the bureau in 1961. He retired in 1964.

Born in Greensboro, N.C., Adm. Chrisman was a graduate of the University of North Carolina and Harvard University Medical School.

Commissioned in the Navy Medical Corps, he trained at the Submarine School in New London, Conn. Much of his later duty at sea and on shore was associated with submarines.

Just before World War II, Adm. Chrisman was the medical officer aboard the aircraft carrier USS Ranger, on neutrality patrol in the Atlantic. He also served a residency in radiology at the Naval Hospital in Washington.

During the war, he was at the Bethesda Naval Hospital and then was sent to the Pacific, where he was medical officer of an advanced naval base in the Solomon Islands.

After the war he served at hospitals in Bainbridge, Md., Newport, R.I., Hawaii and Camp Lejeune, N.C.

Adm. Chrisman held a number of decorations and awards. He was a Mason and a member of Phi Beta Kappa.

He is survived by his wife, Eleanor, of the home in Bethesda; a daughter, Jane McBride, of San Diego; a son, Allan, of Bremerton, Wash., and four grandchildren
