Watson competed in the Indy 500 for the first time in 1948 as a mechanic for a team and entered his own chassis for the first time in 1950, at just 26 years old. However, his big breakthrough came in 1956 when he created the Watson Roadster. The racecar featured a drivetrain set to the left of the driver to improve cornering around the oval, and its driver, Pat Flaherty, won the race. From then, his platform won in '59, '60, '62, '63 and '64. While Watson's biggest racing successes came in the '50s and '60s, he continued working in motorsports through the '80s.
"He was a pioneer. He came out against Kurtis and built the Watson roadster and I was lucky enough to win with it," said famous racing driver A.J. Foyt to National Speed Sport News. Foyt won in a Watson chassis in the '64 Indy 500.
Racing has clearly lost one of its icons, and our condolences go out to his friends and family.
