Robert "Bob" Hill W. Jackson (born April 8, 1934) is an American photographer. In 1964, Jackson, then of the Dallas Times-Herald, was awarded the Pulitzer Prize for Photography for his photograph of the murder of Lee Harvey Oswald by Jack Ruby.
Jackson was riding in the media car of President John F. Kennedy's motorcade through Dealey Plaza. He has stated that three seconds after the third and final volley of shots that he remembered hearing, he looked at the the Texas School Book Depository and he saw some men together on its fifth floor looking out their window pair as they were looking upwards, above themselves. Jackson then looked at the sixth floor, farthest east, half-open window above those men and he briefly saw about half of a rifle, including 8" to 10" of its wood stock, being withdrawn from the window, but Jackson did not remember seeing a scope on the weapon, nor did he see an assassin's face, body, nor arms holding the weapon. Jackson, as did a majority of the Dealey Plaza known witnesses that were interviewed for the Warren Commission, has also maintained that of the three volleys of shots he remembered hearing, the second and third shots were bunched distinctly much closer together in time, than were the first two volleys of shots.
In later life, Jackson was a staff photographer for the Colorado Springs Gazette-Telegraph. He retired from the Gazette in 1999. He has three daughters, two sons from his wife's previous marriage and a son with his current wife. He also has 10 grandchildren.
