Oh, that is cool!
A bit of trivia for fans of the original Cheaper by the Dozen movie:
One of Frank Gilbreth's clients in the early 1900s was the Remington Company, then a famous typewriter manufacturer. Mr Gilbreth was enlisted to help train a fast typist to help Remington win a world-wide typing competition, which was considered a public relations coup at the time. He trained the typist to continually focus on the copy, not the keys. The world champion typist in 1916 typed 150 words per minute, from strange copy, with no mistakes! Along the way, he also helped develop the Dvorak keyboard, a more efficient way of arranging keys (in contrast to the QWERTY arrangement).
Typing 150 wpm isn't *quite* so amazing on a computer keyboard, but it's astounding on a 1920s typewriter!!
