John Fitzgerald Kennedy was born outside Boston in Brookline, Massachusetts on May 29, 1917 to Joseph P. Kennedy Sr., a businessman and politician, and Rose Kennedy (née Fitzgerald), a philanthropist and socialite. His paternal grandfather, P. J. Kennedy, served as a Massachusetts state legislator. Kennedy's maternal grandfather and namesake, John F. "Honey Fitz" 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.
In September 1931, Kennedy started attending 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.
In 1940, Kennedy attempted to enter the army's Officer Candidate School. Despite months of training, he was medically disqualified due to his chronic lower back problems. On September 24, 1941, Kennedy, with the help of then director of the Office of Naval Intelligence (ONI) and the former naval attaché to Joseph Kennedy, Alan Kirk, joined the United States Naval Reserve. He was commissioned an ensign on October 26, 1941, and joined the staff of the Office of Naval Intelligence in Washington, D.C. In addition to the various campaign medals received for his war service, Kennedy was awarded the Navy and Marine Corps Medal for his conduct during and after the loss of PT-109, as well as the Purple Heart for being wounded.
John F. Kennedy spent many years as a congressman representing the state of Massachussets. On December 17, 1959, a letter from Kennedy's staff which was to be sent to "active and influential Democrats" was leaked stating that he would announce his presidential campaign on January 2, 1960. Though some questioned Kennedy's age and experience, his charisma and eloquence earned him numerous supporters.
John F. Kennedy was sworn in as the 35th president at noon on January 20, 1961. In his inaugural address, he spoke of the need for all Americans to be active citizens, famously saying, "Ask not what your country can do for you. Ask what you can do for your country."
President Kennedy was assassinated in Dallas at 12:30 pm Central Standard Time on Friday, November 22, 1963. Kennedy was taken to Parkland Hospital for emergency medical treatment, where he was pronounced dead 30 minutes later. He was 46 years old and had been in office for 1,036 days. Lee Harvey Oswald, an order filler at the Texas School Book Depository from which the shots were fired, was arrested for the murder of police officer J. D. Tippit and was subsequently charged with Kennedy's assassination.
