In 1932 educational psychologist and professor of education at the University of Washington in Seattle August Dvorak and his brother-in-law William Dealey invented the Dvorak Simplified Keyboard Typewriter. After building three examples of the typewriter, the two patented the keyboard in 1936, and along with Nellie Merrick and Gertrude Ford, wrote a book entitled Typewriting Behavior promoting the advantages of their system over the QWERTY keyboard.
