That's him. John Paul Stapp in a 1954 rocket sled test of extreme deceleration. His work led to greatly improved seats and belts.

By riding the decelerator sled, in his 29th and last ride at Holloman Air Force Base in New Mexico, Stapp demonstrated that a human can withstand at least 46.2 g (in the forward position, with adequate harnessing). This is the highest known acceleration voluntarily encountered by a human, set on December 10, 1954. Stapp reached a speed of 632 mph, which broke the land speed record and made him the fastest man on Earth. Stapp believed that the tolerance of humans to acceleration had not yet been reached in tests. He believed it is much greater than thought possible.
