This is a replica of the original telephone transmitter designed by Alexander Graham Bell. He patented his invention in 1876.

This replica dates from 1937 and was made by the General Post Office Engineers Department in Edinburgh.

Alexander Graham Bell, 1847-1922, created a transmitter that could convert sound waves into electrical currents, pass them down a pair of wires to another place, and convert them back into sound waves through a receiver. He called it the telephone.
