Albert C. (Pat.) Patterson, 58, who retired in 1973 from the Office of Emergency Preparedness, died Monday at Washington Adventist Hospital after a long illness.

Since retiring, he had lived in Edgewater, Md., where he was a member of the Coast Guard auxiliary.

Born in Wilkes Barre, Pa., Mr. Patterson attended Girard College in Philadelphia. He served as a medical technician in the Army during 1937-39 and then was in the Army Reserve.

From 1940 to 1944, he worked at St. Elizabeths Hospital, where he took a course in psychiastry. He also trained as a fire fighter at Bolling Field.

Mr. Patterson was called to active Army service in 1944, and served as a surgical technician in the China-Burma-India theater.

After his discharge in 1946, he returned here to work in the executive offices of the President, including the predecessors of the Office of Emergency Preparedness. He also had been employed as a security guard at Lansburgh's store for many years.

Mr. Patterson was a member of the American Legion, the Elks, the Veterans of Foreign Wars, AMVETS and the Knights of Columbus.

He is survived by his wife, Louise M., of the home; a daughter, Ruth M. Foster, of Adelphi; his mother, Ruth P. Shields, and two sisters, Mary Schreffler and Veda Beleski, all of Camden, N.J.; another sister, Lorraine Kessler, of York, Pa., and three grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Lions Eye Bank Foundation in Washington.
