Six-Tenths of a Second Separated Two Dallas Photographers in 1963, and Only One Won the Pulitzer
At 11:21 on the morning of November 24, 1963, Jack Beers was standing on a railing in the basement of Dallas police headquarters with a Mamiyaflex twin-lens reflex, and he tripped his shutter as Jack Ruby stepped into the open. Several feet lower and to his left, Bob Jackson released the shutter on a Nikon S3 six-tenths of a second later. Beers got Ruby walking; Jackson got the bullet.
