On Innovation.

In 1876, the telephone was the subject of a patent dispute between Alexander Graham Bell and Elisha Gray. Although Gray had invented the basic technology in 1874, he did not believe the device was marketable. After Bell demonstrated his own invention at the Philadelphia Centennial Exposition in 1876 and filed a patent for it, Gray changed his mind, and the telephone became the subject of a court battle. Bell was the innovator and Gray the inventor. Who remembers Elisha Gray?
