John Fitzgerald Kennedy Jr. was born at Georgetown University Hospital on November 25, 1960, two weeks after his father was elected president. His parents had a stillborn daughter named Arabella four years before John Jr.'s birth. John Jr. had an older sister, Caroline, and a younger brother, Patrick, who died two days after his premature birth in 1963. His putative nickname, "John-John", came from a reporter who misheard JFK calling him "John" twice in quick succession; the name was not used by his family. John Jr. lived in the White House during the first three years of his life and later remained in the public spotlight up until his death. His father was assassinated on November 22, 1963, and the state funeral was held three days later, on John Jr.'s third birthday. In a moment that became an iconic image of the 1960s, John Jr. stepped forward and rendered a final salute as his father's flag-draped casket was carried out from St. Matthew's Cathedral. The family continued with their plans for a birthday party to demonstrate that the Kennedys would go on despite the death of the President. Kennedy attended private schools in Manhattan, starting at Saint David's School and moving to Collegiate School, which he attended from third through tenth grade. He completed high school at Phillips Academy Andover, Massachusetts. After graduating, he went to Brown University where he majored in American studies. There, he co-founded a student discussion group that focused on contemporary issues such as apartheid in South Africa, gun control, and civil rights. Visiting South Africa during a summer break, he was appalled by apartheid, and arranged for U.N. Ambassador Andrew Young to speak about the topic at Brown. By his junior year at Brown, he had moved off campus to live with several other students in a shared house, and spent time at Xenon, a club owned by Howard Stein. Kennedy was initiated into Phi Psi, a local social fraternity that had been the Rhode Island Alpha Chapter of national Phi Kappa Psi fraternity until 1978. He graduated in 1983 with a bachelor's degree in American studies, and then took a break from work, traveling to India and spending some time at the University of Delhi, where he met Mother Teresa. He also worked with some of the Kennedy special interest projects, including the East Harlem School at Exodus House and Reaching Up.
