The first practical typewriter was patented in the United States in 1868 by Christopher Latham Sholes. His machine was known as the type-writer. It had a movable carriage, a lever for turning paper from line to line, and a keyboard on which the letters were arranged in alphabetical order. But people typed to fast and the keys jammed together. So he separated the keys so people would type slower (so they could type faster with less jams). The resulting configuration was the QWERTY keyboard we have today.
