However, the telegraph was a highly successful system at that time still, its dot and dash Morse code had limitations for sending and receiving one message at a time. When Graham Bell started his work with the electric signal at that time telegraph had already been invented 30 years ago. So, that was the basic reason for the success of Graham Bell's invention of the telephone, as it was come by his improvement of the telegraph. The telephone and the telegraph both are wire-based systems. On the basis of this expertise, he started the work on harmonic telegraph. He became trained by his experiments as well as by his teaching to deaf students. The device was known as ' visible speech'. He invented a device that was earlier made by his father for teaching deaf students. He did many tests as well as experiments on electricity and sound that were influenced by the work of Helmholtz. He shifted to Paris, Ontario, in 1870, and there he opened a workshop. Afterward, he continued his experiment with sound and speech. But after sending the report of his work to Alexander Ellis, he came to know through him that the same experiment was already done by a German scientist Hermann Von Helmholtz. Further, in 1863, inspired by Sir Charles Whetstone's Automator, Bell with his brother made his own Automator, which was based on Baron Wolfgang Von Kempelen's work. This device helps the farmer to a great extent. When he was twelve years old, he saw the problems of the farmers in the field, and then he made an instrument with which the husks of the wheat could remove quickly. He was a thinker as he focused on the problem and tried to find out the solution. Since form his childhood, Bell was a very curious as well as a troubleshooter. Bell's early experiments with sound and speech He had a wide knowledge of sound and its nature that made him a teacher of deaf as well as also inspired him for making a device like a telephone. Graham Bell's mother and wife both were deaf, which influenced his life most, as it was the basic reason that he did research on hearing and speech. There he met with his wife, Mabel Hubbard, who was also a deaf student, and later they got married in 1877. Later at the age of 26, he got the designation of professor in elocution and speech at the University of Boston without having a university degree. There he taught about the techniques of speech as well as vocal physiology.Īnd very soon, several deaf students have shown their interest and got admission to his school. Later he started a school for the deaf in Boston in 1872. He attended Royal High School and the University of Edinburgh. At the age of 16, he began studying the mechanics of speech. And due to his family, academic background in elocution Graham Bell was also interested in the same as he did his study in the same subject. Even his brother was also associated with elocution and speech. His grandfather was a teacher of elocution, and his father was also a professor of elocution and speech at Edinburgh University. Graham Bell was born on 3 rd March 1847 in Scotland. Afterward, there was a legal battle between them over the invention of the telephone, but Graham Bell won in the end. However, both went on the same day on 7 th March 1876 to the patent office, but Alexander Graham Bell went one hour before Elisha Gray, and he patented his telephone first. The device that could transmit speech electrically was the telephone. Both the scientist developed this device independently. In the 1870s, an instrument was developed by two scientists named Elisha Gray and Alexander Graham Bell. But on 11th June 2002, the United States House of Representatives passed a resolution for honoring Meucci's contributions and work for the telephone. As a result, his role in the invention of the telephone was overlooked. He filed an announcement for the invention of his design of the talking telegraph, but due to some problems, he could not renew his caveat. It was the year 1849 when an Italian immigrant named Antonio Meucci began to create a design for a talking telegraph or telephone.
