Abraham Zapruder(1905-1970)

His JFK footage was valued at $16 million (£10 million) by an arbitration panel. The US Government was ordered to pay the amount, the equivalent to $615,384 (£384,615) per second, to the heirs of Abraham Zapruder for taking his footage into the National Archives, where it now resides. It holds the Guinness record of the most expensive reel of film.

I was shooting as they were coming along, and Jacqueline and the President were waving, and as {the car] came in line with my camera, I heard a shot. I saw the President lean over to Jacqueline - I didn't realize what had happened, actually - then the second shot came. I saw his head open up, and I started yelling, "They killed him, they killed him!" and I continued shooting until they were under the underpass. (from a 1966 interview)
