Who Invented Keyboard
The modern keyboard, as we know it today, was invented by Christopher Latham Sholes in the 1860s. Sholes was an American inventor, journalist, and printer who created the first practical and commercially the successful typewriter, the Remington No. 2. He is often credited with inventing the QWERTY keyboard layout, which was designed to prevent mechanical typewriter keys from jamming. However, there were earlier keyboard-like devices, such as the typewriters developed by Henry Mill and Pellegrino Turri, that predate Sholes’ invention.
