Retired Navy Capt. Williston Lamar Dye, 75, a combat veteran of World War II and the Korean War and an investment broker in Washington since 1959, died of congestive heart failure Saturday at Bethesda Naval Hospital.

Capt. Dye was born in California and grew up in Garrett Park, Md. He graduated from the old Central High School in Washington in 1924 and from the U.S. Naval Academy at Annapolis in 1929.

Before World War II, his assignments included service in China and at the Naval Postgraduate School. When the United States entered the war, he was serving aboard a destroyer with the Pacific fleet.

He took part in the operation in which Gen.James H. Doolittle led a carrier-based air raid against Tokyo on April 18, 1942 -- the first American action of the war against the Japanese islands. Capt. Dye also took part in the Battle of Midway and other combat action.

During the Korean War, he commanded an attack transport in Korean waters.

Subsequent duty included a posting as a Navy representative with NATO in Paris and another as director of the Navy's general line and management schools.

Capt. Dye was stationed in Washington as head of the war plans branch in the Office of the Chief of Naval Operations and as a member of the Navy's Disability Retirement Board.

He retired from the service in 1959. Since then, he had been affiliated with the stock brokerage firm of Smith Barney Harris Upham & Co. Inc.

Capt. Dye, who lived in Bethesda, is survived by his wife, the former Margaret Swann, of Bethesda; a son, Williston Dye Jr., also of Bethesda; two daughters, Judy Dye Pureka and Margaret Dye Smith, both of Connecticut; a brother, Gifford, of Harpers Ferry, W.Va., and two grandchildren.
