The Telephone Gambit

The Telephone Gambit: Chasing Alexander Graham Bell's Secret makes a very convincing argument that Bell stole a key component of his successful design of a telephone from Elisha Gray. Using methodical research techniques, Shulman breaks down the many questions and contradictions that he discovered, many of which were raised in challenges to Bell's 1876 patent.
 

Fascinating read, though it should be taken with a full biography of Bell for though his claim to 'inventing' the telephone is tarnished, he was certainly responsible for many, many more innovations.
 

And lest one feel sorry for Elisha Gray (though he did miss out on a huge fortune), the book proves that the real inventor of the telephone was a German named Philipp Reis. Reis had a working device to transmit voices electronically in 1863, thirteen years before Bell's famous shout. Reis was apparently too modest to exploit his discovery commercially.
