Retired Navy Cmdr. Frank D. Whalen, 65, a decorated combat veteran of World War II who was a hospital administrator in Northern Virginia for 15 years after retiring from active duty in 1960, died Friday at Northern Virginia Doctors Hospital after a stroke.

Cmdr. Whalen was a native of Hartford, Conn., and a 1938 graduate of the U.S. Naval Academy at Annapolis. During World War II, he served aboard destroyers and aircraft carriers. His decorations included the Silver Star and two Bronze Star medals.

After the war he was an engineering instructor at the Naval Academy and served with the training command of the Atlantic Fleet. He saw duty in Washington in the office of the Chief of Naval Operations and the office of the Secretary of Defense from 1950 to 1953.

Following his retirement from active duty in 1960, he earned a master's degree in business and hospital administration. He spent four years as an administrator at Alexandria Hospital and then became assistant administrator at Arlington Hospital in 1966. He was administrator of Arlington Hospital from 1974 to 1975 and then was executive director of the Washington House until retiring in 1977.

He was a member of the American Hospital Association and the College of Hospital Administrators.

Cmdr. Whalen had been president of the congregation of the Prince of Peace Lutheran Church. He had lived in Annandale for the past 15 years.

Survivors include his wife, Eve of Annandale; two sons, Navy Cmdr. F. Richard Whalen of Springfield, and Curtis E., of Maitland, Fla., and five grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Prince of Peace Lutheran Church in Springfield.
