On his first model of the Type-Writer, Christopher Sholes put the letters on the keyboard in alphabetical order. In the mechanics of the machine, this caused some problems, because some commonly used characters were situated close together. The hand-built machine functioned too slow, as the letters pliers frequently collided against each other and clamped. Sholes moved a few letters in the mechanism, altering the sequence of the letters on the keyboard.
The machine (the “Sholes, Glidden & Soule Type-Writer”, named after Sholes and his friends) that eventually was put into production around 1873 by the Remington factory, was a precursor of the QWERTY layout that we still find on keyboards.
Sholes, who owned half of the patent of the Type-Writer, sold his half for $12,000 to Remington, while the co-owner of the patent, investor James Densmore, insisted on a royalty, which would eventually earn him $1,500,000.
