Retired Navy Capt. Lowell W. Williams, 74, a former dean at George Washington University and a veteran of World War II and the Korean conflict, died of a heart ailment Tuesday at the Bethesda Naval Medical Center. He lived in Arlington.

Capt. Williams was a native of Oskaloosa, Iowa. He graduated from the U.S. Naval Academy in 1931 and later earned a master's degree in personnel administration from Ohio State University.

During World War II, he commanded a unit that helped establish air bases in the South Atlantic. During the Korean War, he commanded a seaplane tender in the Pacific.

During the 1950s, he served two tours of duty with the planning division of the Bureau of Naval Personnel in Washington and lived in Falls Church and Arlington.

His last tour of duty was as superintendent of the Naval Postgraduate School at Monterey, Calif. He retired in 1961. His decorations included two Legions of Merit and several medals from Brazil.

From 1961 until 1963, he was dean of the School of Government, Business and International Affairs at George Washington. He then served one year as the Washington representative for the Geodyne Corp. of America.

Survivors include his wife, the former Alice Iverna Klingstine, of Arlington.

The family suggests that expressions of sympathy be in the form of contributions to the Navy Relief Society, or to the U.S. Naval Academy Alumni Association.
