Virtual Typewriter Museum: Hansen Writing Ball.

Rev. Rasmus Hansen (1835 - 1890) created this "writing ball", the world's first commercially produced typewriter, so his deaf students can "speak with their fingers."

The most striking feature of the writing ball is the semi-sphere on top of the machine, with 52 keys sticking out like a giant pin cushion. At the lower end of each stem is a character, cast in exactly the right angle to create a perfectly even print on the central printing point under the ball. The escapement mechanism moved the paper frame that held the paper one space until the end of the line was reached. By pushing the button on the left in front of the ball all the way down, the carriage was turned concentrically back to the beginning of the line and moved one line to the left.

Let's go back to 1865 and see how some deaf people could do it long ago. The first manual typewriter in the world came about because of Deaf students at a residential school in Copenhagen in the late 1800s. Pictures! History! Intrigue!" [...] How did people type on it?
