Ralph Teetor, although blind, became a mechanical engineer and in 1945, invented cruise control for automobiles. Actually, a number of earlier names for his speed control device were used before the product name cruise control was thought up in the mid to late 1950s. Chrysler was the first company to offer cruise control, which in 1958 was available on the Imperial model. Cadillac began offering it in 1960.
Indiana-born Teetor had never let blindness stop him. By age 12, he had built his own car. And most people have trouble just driving one safely.
