Author's account of JFK's last footage

Alexandra Zapruder was not born when her grandfather trained his home-movie camera on President John F. Kennedy's motorcade rolling through downtown Dallas 53 years ago, but that 26-second film has become a difficult family legacy.

On Nov 22, 1963, Abraham Zapruder, a devoted supporter of Kennedy and his vision for America, shot a home movie on 8 mm film that became the best-known moving image of the Kennedy assassination.

"Growing up, my parents didn't talk about this because it was grandfather's wish that we approach it with discretion and respect for Kennedy," Alexandra Zapruder, 46, says in an interview.
