Alexander Graham Bell, a Scottish-born speech teacher from Boston, was working on an experimental telegraph one day when it began to function strangely because of a loose part. This accident gave Bell insight into how voices could be reproduced at a distance. He went on to build a simple transmitter and receiver, and as he and his assistant Thomas Watson were getting ready to test it, Bell spilled some acid on himself. In another room, Watson could hear him calling for him through the receiver. The first telephone call was thus made, and Bell was awarded a patent for the electric telephone in March of 1876. This, of course, did not come without controversy from other inventors who were also doing pioneering work on the early telephone. Bell’s claim to being the inventor of the first telephone had to be defended in court some 600 times! While others did make significant contributions, it was Bell who was the first to recognize its commercial viability. Before automatic exchanges were invented, all calls were placed through manual exchanges in which a small light on a switchboard alerted an operator that a caller wanted service.
