The inventor of the cruise control was blind.
Ralph R. Teetor – an accident left Teetor blind at age 5. Inspired by the story of Thomas Edison, Teetor began working with machinery and by age 13 had built an automobile capable of traveling 25 mph.
Teetor’s increased sensitivity of touch and hearing gave him an uncanny ability to diagnose and resolve mechanical design problems. He developed Cruise Control in the 1940s, patenting it under the name Speedostat in 1953.
He died at the ripe old age of 91 on February 15, 1982.
