Elisha Gray

Elisha Gray (August 2, 1835 – January 21, 1901) was an American electrical engineer. He developed a telephone prototype, but it was actually Alexander Graham Bell who earned the telephone patent.

History
His stamp was seen on the wall at Springfield Stamp Museum. When Alexander Abraham Bell from the next stamp introduced himself as an inventor of the telephone, Gray said that Bell had stolen an idea of the telephone from him, but Bell told him to read the patent number.
