John F. "Jack" Quinn, a Marine Corps machine gunner who later led the Naval Academy offshore sailing team, died of heart complications on Sept. 21 at a hospital in Easton. The longtime Gibson Island resident was 89.
Born in Philadelphia in 1926 and raised in the Philadelphia suburbs, John Francis Quinn began his adult life running into the line of fire. At the age of 17 and in the midst of World War II, Mr. Quinn told his mother that he was going to join the Marines.
"She said OK because he had a heart murmur and didn't think he could serve," said his wife, Shirley Adams Quinn, 86, "but he came home enlisted in the Marine Corps."
