David McCulloch Bon, 68, a retired aide for the Organization of American States who served in the Navy during World War II, died Thursday at a hospital in Sarasota, Fla., after a heart attack.
Mr. Bon was a special assistant in the organization's general secretariat here from 1962-78, when he retired and moved to Sarasota.
During the war, he served aboard PT boats in the Atlantic and commanded a landing ship for tanks in the Pacific. After World War II, Mr. Bon was a naval attache in Colombia, and an aide in the Navy's Mediterranean Fleet Command. He retired with the rank of commander.
He was director of public relations for International Petroleum in Lima, Peru, and worked for the State Department in Italy before moving here in 1951 to become Washington manager for the international division of the Sperry Rand Corporation, where he remained until joining the OAS.
Mr. Bon was born in Indianapolis. He graduated from DePauw University in Indiana and earned a bachelor's degree from George Washington University. He attended the Johns Hopkins University School of Advanced International Studies and the State Department's foreign service school.
He was a former resident of Bethesda and a member of the Congressional Country Club, the Army & Navy Club in Washington and the Military Order of World Wars.
Survivors include his wife, the former Frances Kearby, of Sarasota, whom he married in 1948; a daughter, Kearby Parker of Charleston, S.C., and a sister, Mary Cooperider of St. Petersburg.
The family suggests that expressions of sympathy be in the form of contributions to the American Heart Association.
