Alexander Graham Bell Experimental Telephone

Description:

Alexander Graham Bell demonstrated several experimental telephones at the Philadelphia Centennial Exposition in 1876. This unit features a single electro-magnet and could be used both as transmitter and receiver. Bell approached the problem of transmitting speech differently from other telephone inventors like Elisha Gray and Thomas Edison. They were mostly experienced telegraphers trying to make a better telegraph. Bell's study of hearing and speech more strongly influenced his work.
