Mr. Swartz served tours in South Vietnam, Thailand, Laos, Japan, Germany and Guatemala. He was one of the last American civilians evacuated by helicopter during the fall of Saigon in 1975.
After retiring in 1980, he became a staff volunteer on the campaign of George Bush's then-unsuccessful bid for the Republican presidential nomination.

He was born in Chicago and raised in Washington, where he attended Anacostia High School. He served as a Merchant Marine radio operator before joining the CIA in 1951. Over the years, he collected Cambodian and Thai artifacts. He donated the pieces to the Herbert Johnson Museum at Cornell University, where he studied Asian political and military affairs.
He also served on committees of the Harbour Square Owners cooperative in Southwest Washington, where he lived since 1975.
His marriages to Mary Barnes and Mary Jane Swartz ended in divorces.
