Early life and education
John Fitzgerald Kennedy was born on May 29, 1917, at 83 Beals Street in suburban Brookline, Massachusetts, to businessman/politician Joseph Patrick "Joe" Kennedy and philanthropist/socialite Rose Elizabeth Fitzgerald Kennedy. His paternal grandfather P. J. Kennedy was a member of the Massachusetts state legislature. His maternal grandfather and namesake John F. Fitzgerald served as a U.S. Congressman and was elected to two terms as Mayor of Boston. All four of his grandparents were children of Irish immigrants. Kennedy had an elder brother, Joseph Jr., and seven younger siblings: Rosemary, Kathleen, Eunice, Patricia, Robert, Jean, and Ted.
Kennedy's birthplace in Brookline, Massachusetts
Kennedy lived in Brookline for the first ten years of his life and attended the local St. Aidan's Church, where he was baptized on June 19, 1917. He was educated at the Edward Devotion School in Brookline, the Noble and Greenough Lower School in nearby Dedham, Massachusetts, and the Dexter School (also in Brookline) through the 4th grade. His father's business had kept him away from the family for long stretches of time, and his ventures were concentrated on Wall Street and Hollywood. In September 1927, the family moved from Brookline to Riverdale, Bronx, New York. Young John attended the lower campus of Riverdale Country School, a private school for boys, from 5th to 7th grade. Two years later, the family moved to suburban Bronxville, New York, where Kennedy was a member of Boy Scout Troop 2 and attended St. Joseph's Church. The Kennedy family spent summers and early autumns at their home (rented in 1926, then purchased in 1929) in Hyannis Port, Massachusetts, and Christmas and Easter holidays at their winter retreat in Palm Beach, Florida, later purchased in 1933. In September 1930, Kennedy—then 13 years old—attended the Canterbury School in New Milford, Connecticut, for 8th grade. In April 1931, he had an appendectomy, after which he withdrew from Canterbury and recuperated at home.
In September 1931, Kennedy attended Choate, a prestigious boarding school in Wallingford, Connecticut, for 9th through 12th grade. His older brother Joe Jr. had already been at Choate for two years and was a football player and leading student. He spent his first years at Choate in his older brother's shadow, and compensated with rebellious behavior that attracted a coterie. They carried out their most notorious stunt by exploding a toilet seat with a powerful firecracker. In the ensuing chapel assembly, the strict headmaster, George St. John, brandished the toilet seat and spoke of certain "muckers" who would "spit in our sea". The defiant Kennedy took the cue and named his group "The Muckers Club", which included roommate and friend Kirk LeMoyne "Lem" Billings.
During his years at Choate, Kennedy was beset by health problems that culminated with his emergency hospitalization in 1934 at New Haven Hospital, where doctors thought he might have had leukemia. In June 1934, he was admitted to the Mayo Clinic in Rochester, Minnesota; the ultimate diagnosis there was colitis. Kennedy graduated from Choate in June of the following year, finishing 64th in a class of 112 students. He had been the business manager of the school yearbook and was voted the "most likely to succeed".
In September 1935, Kennedy made his first trip abroad when he traveled to London with his parents and his sister Kathleen. He intended to study under Harold Laski at the London School of Economics (LSE), as his older brother had done. Ill-health forced his return to the United States in October of that year, when he enrolled late and attended Princeton University but had to leave after two months due to a gastrointestinal illness. He was then hospitalized for observation at Peter Bent Brigham Hospital in Boston. He convalesced further at the family winter home in Palm Beach, then spent the spring of 1936 working as a ranch hand on the 40,000-acre (160 km2) Jay Six cattle ranch outside Benson, Arizona. It is reported that ranchman Jack Speiden worked both brothers "very hard".
In September 1936, Kennedy enrolled at Harvard College and his application essay stated: "The reasons that I have for wishing to go to Harvard are several. I feel that Harvard can give me a better background and a better liberal education than any other university. I have always wanted to go there, as I have felt that it is not just another college, but is a university with something definite to offer. Then too, I would like to go to the same college as my father. To be a 'Harvard man' is an enviable distinction, and one that I sincerely hope I shall attain." He produced that year's annual "Freshman Smoker", called by a reviewer "an elaborate entertainment, which included in its cast outstanding personalities of the radio, screen and sports world." He tried out for the football, golf, and swimming teams and earned a spot on the varsity swimming team. Kennedy also sailed in the Star class and won the 1936 Nantucket Sound Star Championship. In July 1937, Kennedy sailed to France—taking his convertible—and spent ten weeks driving through Europe with Billings. In June 1938, Kennedy sailed overseas with his father and older brother to work at the American embassy in London, where his father was President Franklin D. Roosevelt's U.S. Ambassador to the Court of St. James's.
In 1939, Kennedy toured Europe, the Soviet Union, the Balkans, and the Middle East in preparation for his Harvard senior honors thesis. He then went to Czechoslovakia and Germany before returning to London on September 1, 1939, the day that Germany invaded Poland to mark the beginning of World War II. Two days later, the family was in the House of Commons for speeches endorsing the United Kingdom's declaration of war on Germany. Kennedy was sent as his father's representative to help with arrangements for American survivors of the SS Athenia before flying back to the U.S. from Foynes, Ireland, to Port Washington, New York, on his first transatlantic flight.
When Kennedy was an upperclassman at Harvard, he began to take his studies more seriously and developed an interest in political philosophy. He made the Dean's List in his junior year. In 1940, Kennedy completed his thesis, "Appeasement in Munich", about British participation in the Munich Agreement. The thesis became a bestseller under the title Why England Slept. In addition to addressing Britain's failure to strengthen its military in the lead-up to World War II, the book also called for an Anglo-American alliance against the rising totalitarian powers. While Kennedy became increasingly supportive of U.S. intervention in World War II, his father's isolationist beliefs resulted in the latter's dismissal as ambassador to the United Kingdom, creating a split between the Kennedy and Roosevelt families.
In 1940, Kennedy graduated cum laude from Harvard College with a Bachelor of Arts in government, concentrating on international affairs. That fall, he enrolled at the Stanford Graduate School of Business and audited classes there. In early 1941, Kennedy left and helped his father write a memoir of his three years as an American ambassador. He then traveled throughout South America; his itinerary included Colombia, Ecuador and Peru.
