On this day in 1876, Scottish inventor Alexander Graham Bell received the patent for his invention of the ‘telephone’. In 1875, Bell had developed an acoustic telegraph, which laid the foundations for the invention of the telephone communication device. Once he developed the device, Bell tried to receive a patent. However, controversy surrounds the invention of the telephone, as there have been claims that the credit for the invention in fact rests with another inventor: Elisha Gray. Gray had also been working on a device for transmitting voice messages using a water transmitter and both filed the patent the same day - February 14th 1876 - leading to speculations about who got there first; some have even suggested that Bell stole the invention from Gray. However, whether erroneously or not, Bell is the one credited for the invention of the telephone. Bell was issued patent 174,465 on March 7th for “the method of, and apparatus for, transmitting vocal or other sounds telegraphically…by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound.” Three days later, on March 10th, Bell succeeded in getting his telephone to work when he summoned his lab assistant Thomas Watson from the next room, thus making the first, albeit very brief, telephone call. Bell said “Mr Watson - come here - I want to see you”, which was clearly transmitted to his assistant at the other end of the line.
