Click here to see an actual black and white photograph of Dr. August Dvorak, the inventor of the Dvorak Simplified Keyboard . "Dr. August Dvorak, an educational psychologist and professor of education at the University of Washington, teaches a class of typists his new Simplified Keyboard Layout. In May 1932 Dr. Dvorak filed a patent for the new layout, which claimed to result in faster, easier to learn typing. This photo may have been taken for a promotional piece." Viva La Dvorak!

In the Typing Analyst of DVzine, I put in all the answers I posted in Yahoo! Answers before I began writing this.
