In the 1870s, two inventors Elisha Gray and Alexander Graham Bell both independently designed devices that could transmit speech electrically (the telephone). Both men rushed their respective designs to the patent office within hours of each other, Alexander Graham Bell patented his telephone first. Elisha Gray and Alexander Graham Bell entered into a famous legal battle over the invention of the telephone, which Bell won. |

Sholes was a U.S. mechanical engineer who invented the first practical modern typewriter, patented in
1868 and was manufactured (by Remington Arms Company) in 1873. The type-bar system and the universal keyboard were the machine's novelty, but the keys jammed easily.
James Densmore suggested splitting up keys for letters commonly used together to slow down
typing, producing the standard "QWERTY" keyboard. |
