Dvorak,
An early computer geek, he proposed a new layout for the computer keyboard (from memory, I believe it was in the 80's). This was before the Internet and when 'Personal' computers were very rare.
His design was based on the frequency of letters used in the English language and made a whole lot of sense. Although a superior design it was unable to overcome the "human factor". That is, the majority of 'touch typists' who were unable (or unwilling) to relearn in order to improve efficiency.
