Alexander Graham Bell
Alexander Graham Bell
Alexander Graham Bell was born on March 3rd,1847 in Edinburgh, Scotland and died 75 years later in Nova Scotia, Canada on August 2nd, 1922. He is well known as the inventor of the telephone and had many other inventions as well. His mother and wife were both deaf and were very inspiring to him. His mother was a pianist despite her deafness. Alexander’s grandfather also influenced him greatly. He was a known professor and taught elocution. Alexander Graham Bell created his first invention when he was only 12 years old. He noticed how the husking of the wheat grain was very inefficient while messing around with a friend in a grain mill. He was inspired to create a device that could increase the efficiency. So, he created a device with rotating paddles with a set of nailbrushes that husked the wheat. As a young adult, Graham Bell joined his father in promoting visible speech and teaching the deaf to read lips. In 1871, Alexander accepted a position to teach at the Boston school and began working independently as a tutor for the deaf. While tutoring, he established relationships with his students’ parents. Gardiner Hubbard, one of his students’ fathers, told Bell that he was trying to find a way to improve the telegraph transmissions because they could only carry one message at a time. Bell came up with the idea that many telegraph transmissions could be sent on the same wire if they were transmitted on different harmonic frequencies. Bell spent 2 years, 1873 and 1874, trying to make the Harmonic telegraph. While he was doing this, he came up with another idea, which was to transmit voice over wires. Bell then began working with Thomas Watson, an electrician, to create what would be known as the telephone. While Bell came up with the ideas, Watson brought his ideas to life.
