John Fitzgerald Kennedy (May 29, 1917 – November 22, 1963), often referred to by his initials as JFK or by the nickname Jack, was an American politician who served as the 35th president of the United States from 1961 until his assassination near the end of his third year in office. Kennedy was the youngest person to assume the presidency by election. He was also the youngest president at the end of his tenure, and his lifespan was the shortest of any president. Kennedy served at the height of the Cold War, and the majority of his work as president concerned relations with the Soviet Union and Cuba. A Democrat, he represented Massachusetts in both houses of the U.S. Congress prior to his presidency. Born into the prominent Kennedy family in Brookline, Massachusetts, Kennedy graduated from Harvard University in 1940 before joining the U.S. Naval Reserve the following year. During World War II, he commanded a series of PT boats in the Pacific theater. Kennedy's survival of the sinking of PT-109 and rescue of his fellow sailors made him a war hero for which he earned the Navy and Marine Corps Medal, but left him with serious injuries. After a brief stint in journalism, Kennedy represented a working-class Boston district in the U.S. House of Representatives from 1947 to 1953. He was subsequently elected to the U.S. Senate and served as the junior senator for Massachusetts from 1953 to 1960. While in the Senate, Kennedy published his book, Profiles in Courage, which won a Pulitzer Prize. In the 1960 presidential election, he narrowly defeated Republican opponent Richard Nixon, who was the incumbent vice president. Kennedy's humor, charm, and youth in addition to his father's money and contacts were great assets in his campaign. Kennedy's campaign gained momentum after the first televised presidential debates in American history. He was the first Catholic elected president.
