John Fitzgerald Kennedy Jr. (November 25, 1960 - July 16, 1999), often referred to as JFK Jr. or John John, was an American lawyer, journalist, and magazine publisher. He was a son of President John F. Kennedy and First Lady Jacqueline Kennedy, and a younger brother of former Ambassador to Japan, Caroline Kennedy. His father was assassinated three days before his third birthday. From his early childhood years at the White House, Kennedy was the subject of great media scrutiny, and he became a popular social figure in Manhattan.

After President Kennedy was assassinated in 1963, Mrs. Kennedy moved her family to a luxury apartment on the Upper East Side of Manhattan in New York City, where John Kennedy, Jr. grew up. In 1967, his mother took him and Caroline on a six-week "sentimental journey" to Ireland, where they met President Eamon de Valera and visited the Kennedy ancestral home in Dunganstown.  After his uncle Robert was assassinated in 1968, his mother took him and his sister out of the United States, saying: "If they're killing Kennedys, then my children are targets ... I want to get out of this country." The same year, she married Greek shipping tycoon Aristotle Onassis, and the family went to live on his private island of Skorpios. Kennedy is said to have considered his stepfather "a joke".  In 1971, Kennedy returned to the White House with his mother and sister for the first time since the assassination. President Richard Nixon's daughters gave Kennedy a tour that included his old bedroom, and Nixon showed him the Resolute desk under which his father had let him play. When Onassis died in 1975, he left Kennedy $25,000, though Jacqueline was able to renegotiate the will, and acquired $20 million for herself and her children.  In 1976, Kennedy and his cousin visited an earthquake disaster zone at Rabinal in Guatemala, helping with heavy building work and distributing food. The local priest said that they "ate what the people of Rabinal ate and dressed in Guatemalan clothes and slept in tents like most of the earthquake victims", adding that the two "did more for their country's image" in Guatemala "than a roomful of ambassadors". On his sixteenth birthday, Kennedy's Secret Service protection ended. He spent the summer of 1978 working as a wrangler in Wyoming.  Before attending Brown University, Kennedy accompanied his mother to Africa. On a pioneering course, he rescued his group, which had gotten lost for two days without food or water, and won points for leadership. In 1979, the John F. Kennedy Presidential Library and Museum was dedicated, and Kennedy made his first major speech, reciting Stephen Spender's poem "I Think Continually of Those Who Were Truly Great".
