March 10th - On this day in 1876, Alexander Graham Bell makes history by making the first successful call on his invention, the telephone.
On March 10, 1876, three days after his patent was issued, Bell succeeded in getting his telephone to work, using a liquid transmitter similar to Elisha Gray’s design. Vibration of the diaphragm caused a needle to vibrate in the water, varying the electrical resistance in the circuit. When Bell spoke the famous sentence “Mr Watson—Come here—I want to see you” into the liquid transmitter, Watson, listening at the receiving end in an adjoining room, heard the words clearly.
Since it’s invention in early 1876, the creator of the telephone has been questioned as it was first developed by several people, but Alexander Graham Bell was the first to successfully use the device.
