Selden Chapin was born in Erie, Pennsylvania, the son of Captain Frederic Lincoln Chapin (who was commander of the battle ship Wyoming) and his wife Grace Card (Selden) Chapin. He graduated from the United States Naval Academy in 1919 and served in the U.S. Navy from 1919 to 1925. He married Mary Paul Noyes, March 30, 1927.
He was appointed a foreign service officer in March 1925. After the liberation of Paris in August 1944, he served as Charge d'Affaires in the American Embassy in the absence of an ambassador, since France formally broke off diplomatic relations with the U.S. after the Torch Invasion of North Africa in November 1942. Jefferson Caffery assumed the ambassadorship on 30 December 1944. Later Chapin was the U.S. ambassador to Hungary, Iran, Netherlands, Peru and Panama. Chapin and his wife are interred in Arlington National Cemetery.[1]
