Elisha Gray was an American electrical engineer and co-founder of what became the Western Electric Manufacturing Company. He filed a patent caveat describing a telephone-like device on February 14, 1876, the same day Alexander Graham Bell's own telephone patent application reached the United States Patent Office, a coincidence that made him Bell's principal rival in the resulting decades of litigation over who invented the telephone first.

In 1870 he invented a needle annunciator for hotels and elevators and a microphone printer. He also built a musical telegraph, one of the world's first electrical musical instruments, and in 1887 he invented the teleautograph, a device that sent handwriting over telegraph wires.

Held Differently
The Telephone, Inventions Why this is disputed. Gray's February 14, 1876 caveat described a similar voice-transmission method filed the same day as Bell's application; the United States Patent Office and later courts upheld Bell's patent, but the question of who reached the idea first has never been settled to universal satisfaction.
