The Hansen Writing ball was developed to help Hanson’s deaf and dumb pupils write and was seriously cool looking. via typewriter museum
Although the Sholes & Glidden is generally regarded as the first production typewriter in history, the Hansen writing ball in fact beat the S&G by no less than four years. The reverend Rasmus Hans Malling Johan Hansen (1835-1890) worked as a teacher and as director of an institution for the deaf and dumb in Copenhagen. It was his desire to enable his pupils to ‘speak with their fingers’ that led him to develop his writing ball.
