Donald G. Storey, 69, a retired Navy commander who later worked for the Navy department as a civil engineer at the Washington Navy Yard, died of pneumonia last Tuesday at the Bethesda Naval Hospital.

Cmdr. Storey was born in Chicago and earned a degree in civil engineering from the Armour Institute of Technology, now the Illinois Institute of Technology. He worked for the city of Chicago until 1942, when he joined the Navy.

During World War II, he served with a naval construction battalion in the South Pacific. After the war, he served at a number of posts in the United States and Alaska. He settled in Arlington in 1959 and retired from the Navy in 1963. He then worked for the Navy as a civil engineer until he retired again in 1969.

Cmdr. Storey was a member of the Naval Reserve Officers Association, the Explorer's Club, the Retired Officers Association, the Society of American Military Engineers and the American Association of Retired Persons.

Survivors include his wife, Pauline, of the home in Arlington; six brothers, Victor, of Largo, Fla., Richard, Burton and Loren, all of Zion, Ill., Roger, of Clinton, Md., and James, of Lombard, Ill., and five sisters, Jessie Burgess, Virginia Wirth, Maxine Krause and Jean Storey, all of Zion, Ill., and Adelle Groome, of Ft. Walton Beach. Fla.

The family suggests that expressions of sympathy be in the form of contributions to The Columbia Lighthouse for the Blind Inc., 1421 P St. NW, Washington, D.C.
