August Dvorak (May 5, 1894 – October 10, 1975) was an American educational psychologist and professor of education at the University of Washington in Seattle, Washington. He and his brother-in-law, William Dealey, are best known for creating the Dvorak Simplified Keyboard layout in the 1930s as a replacement for the QWERTY keyboard layout. In the 1940s, Dvorak designed keyboard layouts for people with the use of one hand.
