DALLAS (AP) - Pulitzer-winning historian David McCullough will headline a ceremony next year in Dallas to mark 50 years since the assassination of President John F. Kennedy.
Dallas Mayor Mike Rawlings announced Tuesday that McCullough will serve as keynote speaker for a commemoration scheduled for Nov. 22, 2013.
The day will be exactly 50 years since a gunman fired on Kennedy's motorcade as it passed through Dealey Plaza in downtown Dallas.
The Warren Commission that investigated the president's death concluded that Lee Harvey Oswald fired at Kennedy's motorcade from the sixth floor of the Texas School Book Depository and acted alone.
McCullough has written acclaimed biographies of Presidents Harry Truman and John Adams. He's won two Pulitzer Prizes, among many other awards.
