Bob Jackson was in JFK’s motorcade the morning of 11.22.63. He was one of just four people who, after hearing the shots, looked up and saw Lee Harvey Oswald’s rifle sticking out the sixth floor of the Texas Schoolbook Depository. And, two days later, he was the only person who snapped his shutter at the exact moment Jack Ruby fired his gun, shooting Oswald in the basement of the Dallas Police Department.

Bob won a Pulitzer Prize for taking what would quickly become one of the most infamous photos in American history. Bob is living history. This is his story. And I relished every minute of it.
