Among his many honors as President of the United States of America, John Fitzgerald Kennedy remains the youngest man ever elected to the office of chief executive and the youngest man to die while he was still fulfilling his mandated duties. Serving as American president, John F. Kennedy held his office for 1000 days, dying on November 22, 1963, assassinated at the age of 46. John Fitzgerald Kennedy was born on May 29, 1917 in Brookline, Massachusetts, the second son of nine children of the wealthy Roman Catholic Kennedy family. Joseph Patrick Kennedy, Kennedy's father, was a self-improving multimillionaire who had built a financial empire through ventures in banking, the stock market, shipbuilding, the motion picture industry, and liquor distribution. Kennedy's mother, Rose Fitzgerald, was of Irish descent like her husband and the daughter of former Boston Mayor John F. Fitzgerald. As the patriarch of the family, Joseph Kennedy pushed his children to achieve and often encouraged them to compete with each other. John Kennedy's childhood was spent in exclusive private schools, including the Canterbury School in New Milford, Connecticut, and Choate Hall Preparatory School in Wallingford, Connecticut. While Joseph Kennedy served as US ambassador to Great Britain, John Kennedy, then 18, spent a year at the London School of Economics. John returned to America to attend Princeton University, but left during his freshman term due to a case of severe jaundice. His illness is believed to have been caused by a condition that the Kennedy family kept secret all their lives. John Kennedy was one of 1 in 100,000 people affected by Addison's disease, a rare but serious disorder that affects the endocrine system. Kennedy entered Harvard in 1936... middle of paper... days after his arrest as a suspect in the assassination of President Kennedy.

Kennedy and Edward M. Kennedy. In the years following his assassination, President John F.

Kennedy Center for the Performing Arts, the Kennedy Space Center, the John F. Kennedy Library in Washington and John F. Kennedy University in San Francisco.
