It was in the summer when he met Watson. Over the summer they thought of the idea. But the first idea was to send 2 messages on the telegram at a time. Pretty soon, the idea faded away because somebody else was already working on sending 4 messages at a time. So, then they got the idea of a invention that would send your voice across a wire. It seemed impossible but it worked!
In 1873 and 1874, Bell began working on a way to send voice signals over a telegraph line (the "harmonic telegraph"). But it was not until he began working with Thomas Watson that he was able to create the apparatus to use the designs. By 1876, he had received a US Patent for the invention.
