Derived - In the 1870s, two inventors Elisha Gray and Alexander Graham Bell both independently designed devices that could transmit speech electrically (the phone). Both men rushed their respective designs to the patent office within hours of each other, Alexander Graham Bell patented the telephone in advance. Elisha Gray and Alexander Graham Bell entered into a famous legal battle over the invention of telephones, which Bell won.
Alexander Graham Bell - Evolution Telegraph to Telephone
The telegraph and telephone are both wire-based electrical systems, and Alexander Graham Bell's success with the telephone came as a direct result of efforts to improve the telegraph.
When Bell began experimenting with electrical signals, the telegraph has been established means of communication for some 30 years. Although a highly successful system, the telegraph, with point-and-dash Morse code, was basically limited to receiving and sending one message at a time. Bell's extensive knowledge of the nature of sound and his understanding of music enabled him to conjecture the possibility of transmitting multiple messages over the same wire at the same time. Although the idea of multiple telegraph had been in existence for some time, Bell offered his own musical or harmonic approach as a possible practical solution. "Harmonic telegraph" was based on the principle that several notes could be sent simultaneously along the same wire if the notes or signals is different in the field.
Alexander Graham Bell - Speak with Power
In October 1874, Bell's research had progressed so far that he could inform his future father-in-law, Boston attorney Gardiner Greene Hubbard, about the possibility of a telegraph. Hubbard, who upset then given absolute control by the Western Union Telegraph Company, instantly saw the potential for breaking such a monopoly and gave Bell the financial support they need. Bell continued his work on multiple telegraph, but he did not tell Hubbard that he and Thomas Watson, a young electrician who requested her services, also explores the idea occurred to him that summer - which is developing a device that would transmit speech electrically.
While Alexander Graham Bell and Thomas Watson worked on the harmonic telegraph at the urgent insistence of Hubbard and other support, Bell continued to meet in March 1875 with Joseph Henry, the respected director of the Smithsonian Institution, who listened to Bell's ideas for a telephone and offered encouraging words. Henry encouraged by the positive opinion, Bell and Watson continued their work. In June 1875 the goal of creating a device that would transmit speech electrically will be realized. They have proven that different tones would vary the strength of an electric current in a wire. To achieve success because they only need to build a working transmitter with a membrane capable of a variety of electronic currents and a receiver that would reproduce the variations in audible frequencies.
First Beep
On June 2, 1875, Alexander Graham Bell while experimenting with a technique called "harmonic telegraph" discovered he could hear sound over a wire. The sound is a twanging clock spring.
Bell's greatest success achieved on March 10, 1876, marked not only the birth of the telephone but the death of a telegraph, too. Communications potential contained in his demonstration could "talk with electricity" far beyond anything that simply increasing the ability of a system of dot-and-dash may imply.
First, the sound - Mr. Watson, come here. I want to see you.
Alexander Graham Bell's notebook entry is March 10, 1876 describes a successful experiment with the telephone. Speaking through the instrument of his assistant, Thomas A. Watson, in the next room, Bell said those famous first words, "Mr. Watson - come here - I want to see you."
Alexander Graham Bell - Biography Brief
Was born on March 3, 1847 in Edinburgh, Scotland, Alexander Graham Bell was the son and grandson of authorities in elocution and speech correction over. Educated to pursue a career in the same specialty, his knowledge of the nature of the sound makes it not only teach the deaf, but also to create a phone
