Who was the fastest man on earth, was responsible for the Murphy's Law "whatever can go wrong will go wrong, and championed the seatbelt you wear daily?

A resident of Alamogordo, who worked at Alamogordo New Mexico’s Holloman Air Force Base, made history in the U.S. space program and history for travel at a speed faster than a .45-caliber bullet in an experiment to test the limits of human endurance. That same Alamogordo resident was known as the "fastest man on Earth" during the research phase of the US space program to the moon. He accelerated in five seconds from a standstill to 632 m.p.h. The New York Herald Tribune called this Alamogordo resident "a gentleman who can stop on a dime and give you 10 cents change." He won what will perhaps be even more lasting fame in a test five years earlier, when he suffered injuries owing to a mistake by a US Airforce Captain Murphy. The result was the phrase “Murphy's Law,  Whatever Can Go Wrong, Will Go Wrong .” Who was this remarkable Alamogordo resident? Seven years before the US sent the other famous Alamogordo resident Ham, (the three-year-old chimpanzee) into space aboard the Mercury Capsule Number 5, this Alamogordo resident, was himself a live monkey, in many speed and endurance tests that tested the limits of man verses speed and gravity.
