If August Dvorak (1894-1975) had had his way, then the letters on the top row of our keyboards would read "P,Y,F,G,C,R,L." Along with his brother-in-law, William Dealey, Dvorak patented this alternative to the standard "QWERTY" keyboard in 1936, claiming it made for quicker and more comfortable use.

He was not, in fact, a typewriter manufacturer, but a psychologist and educationalist, but was no dilettante, and based his work on studies of both physiology and language. There is no denying that the familiar "QWERTY" layout, dating to the 1870s, does not seem especially logical, although it is now generally accepted that the notion it was deliberately made to slow the typist down is untrue, and it was, in fact, to reduce paper jams.

To this day, most operating systems on computers will permit the user to switch to the Dvorak layout, and it still has its supporters, who insist it is more efficient and less likely to cause Repetitive Strain Injury (RSI) though this is scientifically unsubstantiated.

Until recently, keyboards mainly for use in French-speaking countries generally offered another configuration, with the "Q", being far more widely used in French, rendered more accessible.

There was a distant family relationship between August Dvorak and the composer Antonin.
