Dr. Harry F. Davies, 83, a retired ear, nose, and throat doctor and former president of the medical staff at Prince George's General Hospital, died of a heart ailment Friday in his home in Upper Marlboro.

Dr. Davies maintained a private practice in Washington from the 1920s until retiring about 12 years ago. He also taught courses in otolaryngology at Georgetown University's medical school during the 1930s.

He was a department head at Prince George's General Hospital and sered as president of the medical staff from 1952 to 1953.

His professional memberships included the Medical Society of the District of Columbia, the International College of Surgeons, and the Southern Medical Association.

Dr. Davies was a native of Pittsburgh and a 1920 graduate of Georgetown University's medical school. He then studied otolaryngology at the University of Pennsylvania's Graduate School of Medicine.

He served in the Army after World War I.

He had lived in Upper Marlboro for the past 40 years. He belonged to the Bethesda Country Club, the Solomons Island Yacht Club and the Army Navy Country Club.

He is survived by his wife of 54 years, the former Frances Scheele, of the home; a daughter, Eileen Bucher, of Upper Marlboro; three sons, Gene, of Bryans Road, Md., and Harry F. Jr. and Neal, both of Bethesda; two brothers, Drew, of Manassas, and Joseph, of Florida; a sister, Katherine French, of Winston-Salem, N.C., and 15 grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Georgetown University School of Medicine.
