| Video Discription | Bell moved with his family to Canada when he was 23 years old. Here he continued his previous work on hearing and speech. His father was a renowned phonetician, and his mother had gradually become deaf through his teenage years. Both his parents had a strong impact on their son’s work. By 1871, however, Bell had moved away to Boston where he trained teachers of the deaf. It was while in Boston that Bell’s experiments with sound waves and electricity led to his development of a telegraph-like system to transmit the vibrations associated with speech. His ‘harmonic telegraph’ was patented on the same day as fellow inventor Elisha Gray filed a similar caveat with the US Patent Office. Although Bell was awarded patent 174,465 on 7 March for his invention, there continues to be considerable debate over whether Bell stole the telephone from Gray. It wasn’t until three days later, while using a liquid transmitter similar to Gray's design, that Bell succeeded in getting his idea to work. He recorded in his journal that he shouted the phrase, 'Mr. Watson, come here – I want to see you!’ Watson soon appeared, saying that he heard the words clearly. Despite legal challenges the courts always upheld Bell’s claim to the invention. Bell never used the liquid transmitter in public demonstrations, focusing instead on his own electromagnetic design. Fellow inventor Thomas Alva Edison later made a significant improvement with his invention of the carbon microphone. |
