1967: The body of President John F. Kennedy is moved to a permanent burial place and memorial at Arlington National Cemetery. Kennedy had originally been buried in a smaller plot at the cemetery on Nov. 25, 1963, and his grave was visited by an estimated 16 million people in the first three years after his death. The grave is marked with the "eternal flame" and his wife, first lady Jacqueline Kennedy Onassis, was buried next to him in 1994. The remains of Kennedy's brothers, Sens. Robert F. Kennedy and Edward M. "Ted" Kennedy, are buried nearby.
