Paul M. Fitts was a psychologist at Ohio State University (later at the University of Michigan). He developed a model of human movement, Fitt's Law, based on rapid, aimed movement, which went on to become one of the most highly successful and well studied models of human motion. He was one of the pioneers in improving aviation safety by paying more attention to human factors while he was a Lieutenant Colonel in the US Air Force. He died unexpectedly at the age of 53 in 1965. He was President of Division 21 (Division of Applied Experimental and Engineering Psychology) of the American Psychological Association (APA), in 1957-1958, which has a Paul Fitts honorary award.
