Alphonse Chapanis (March 17, 1917 – October 4, 2002) was an American pioneer in the field of industrial design, and is widely considered one of the fathers of ergonomics or human factors – the science of ensuring that

, Chapanis found that certain cockpit controls were confused with each other, due partly to their proximity and similarity of shape. Particularly, the controls for flaps and

were confused, the consequences of which could be severe. Chapanis proposed attaching a wheel to the end of the landing gear control and a triangle to the end of the flaps control, to enable them to be easily distinguished by touch alone. Thereafter for that aircraft there were no further instances of the landing gear being mistakenly raised while the aircraft was still on the ground. This particular shape-coding of cockpit controls is still used today. In 1949 he published the first textbook on the subject of
