The typewriter separated writing from handwriting

On August 26, 1843, Charles Thurber patented a “Machine for Printing by Hand by Pressing Upon Keys Which Contain the Type.” It was an ancestor of the typewriter, although not one that invited brisk typing.

The letters sat on rods around a horizontal wheel. To print one, the operator found its key, moved it to a guide, pressed the type onto the paper, then advanced the carriage. Fresh ink required whirling the wheel. The mechanism replaced penmanship with a sequence of selections and small mechanical chores.

Thurber’s account of the intended market is more interesting than the machine. The patent says it was for people unable to write with a pen: “specially” blind people, who could identify raised letters on the keys, and “the nervous, likewise.” It could also make public records and keep accounts of daily events legible to other readers.

For a blind operator, the accommodation was at the input. The machine produced ordinary inked letters, not a tactile text designed for the author to read back. It offered a way to put thoughts into the dominant paper system—to write for sighted readers and institutions—without making that system reciprocal.

This was not quite a keyboard in the modern sense, and the surviving patent model looks more like tabletop apparatus. But the important separation is already there. A pen asks the hand both to choose a letter and to draw it acceptably. Thurber assigned the drawing to the machine.

Speed came later. The first advertised benefit was that bad, difficult or impossible handwriting no longer had to disqualify the words.
