Bill Eppridge, one of the most legendary photojournalists, died Wednesday. He was 75. Eppridge was a staff photographer for LIFE where he covered many assignments, including the Vietnam War, heroin addicts in New York City and the presidential campaign of Sen. Robert F. Kennedy. One of his most iconic images was of Kennedy's lying on the floor in a hotel kitchen immediately after being shot, and the busboy looking up for help.

The image was not only haunting and beautiful, but captured history in one frame. Eppridge once described a thought he had while photographing the Kennedy assassination in 1968: "You are not just a photojournalist, you're a historian."

The world mourns one of the finest and most iconic photographers of our time.
