Stoddard Gregg Cortelyou, 85, a retired Marine Corps colonel and decorated combat veteran of two wars who also was a former George Washington University official, died Jan. 3 at the Belvoir Woods Health Care Center in Fort Belvoir. He had Alzheimer's disease.

Col. Cortelyou, a Los Angeles native, was commissioned in the Marine Corps after graduating from the University of California at Berkeley in 1940 with a degree in aeronautical engineering.

He was serving with the Marine detachment aboard the USS Nevada when that battleship was among the vessels that came under attack when the Japanese struck Pearl Harbor, Hawaii, on Dec. 7, 1941.

Col. Cortelyou went on to participate in the bloody World War II campaign for Tarawa in the Pacific, serving as a company commander in the initial amphibious wave to strike the island. Later in the Pacific campaigns, he served as a staff officer.

After the war, he received his aviator's wings. During the Korean War, he commanded a jet fighter-bomber squadron, flying the legendary F9F "Panther" jet.

Col. Cortelyou, who received a master's degree in international affairs from George Washington University in 1963, was a graduate of both the National War College and the Marine Corps Staff and Command College at Quantico. He taught at both Quantico and the War College and was a member of the War College faculty when he retired from active duty in 1968.

He then moved to the Midwest and was head of the University of Minnesota's Minnesota Management Development Program until 1975. Three years later, he moved to this area and became assistant director of GWU's continuing engineering education program. He retired in 1987.

Col. Cortelyou, who lived in the Fairfax retirement community at Fort Belvoir, was the recipient of the Distinguished Flying Cross, the Bronze Star and five Air Medals.

He was a life member of the Marine Corps Aviation Association, the Marine Corps Association, the USS Nevada Association and the Retired Officers Association.

His first wife, the former Lorraine Martens, died in 1975.

Survivors include his wife, Jeanmarie McNulty Cortelyou of Fort Belvoir; two children from his first marriage, Catherine G. Totherow of Phoenix and Stephen G. Cortelyou of Knoxville, Tenn.; four stepdaughters; eight grandchildren; and two great-grandchildren.
