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.

The next time you are in Copenhagen, please visit the Royal School for the Deaf where Malling-Hansen was the principal. There is a commemorative monument in the school courtyard. If you can't make it to Denmark, feel free to visit the school in a virtual way through the Society's web site and/or the School's own website, which is www.skolenpaakastelsvej.kk.dk.
