Invention and Engineering
The Blickensderfer typewriter was invented by George Canfield Blickensderfer (1850–1917) and patented on April 12, 1892. Blickensderfer was a nephew of John Celivergos Zachos, the inventor of the stenotype. Two models, Model 1 and Model 5, were unveiled to the public at the 1893 World's Columbian Exposition in Chicago. The Model 5 was a stripped-down version of the bigger, more complex Model 1. These machines were intended to compete with larger Remington, Hammond and Yost typewriters, and were the first truly portable, full-keyboard typewriters. The design also enabled the typist to see the typed work, at a time when most typewriters were understrike machines that concealed the writing. When Blickensderfer unveiled his small Model 5, its compactness and novel features attracted huge crowds and many orders.
