Working with his assistant, Thomas Watson, Bell initially had a different goal in mind: to develop a “harmonic telegraph” that could send a number of messages at the same time, each at its own pitch. On March 7, 1876, Bell became the first inventor to receive a US patent for the technology that powered the telephone. But it was a teacher interested in sound and speech instruction for the deaf, Alexander Graham Bell, who would combine the power of electromagnetism with a machinery of vibration and thereby establish the basis of modern telephone technology. In the next decades, Johann Philipp Reis and Antonio Meucci developed electromagnetic devices that could transmit music and some voice communication. In 1840, Charles Grafton Page used electrified wire connected to a magnet to produce sound. Samuel Morse’s telegraph, patented in 1837, used electric signals to transfer coded messages.

Inventors like Bell helped create the foundations for modern telephone communications, which today function as important systems that help people everywhere connect from a distance. In 1888, he also became a founding member of the National Geographic Society as he sought to further expand scientific study. He made advancements with photophones, metal detectors, hydrofoils and aeronautics. In the years that followed, Bell continued his innovative pursuits. was established, and Bell served as the company’s technical adviser until the early 1880s, when he lost interest in the company’s work and decided to sell his shares. Bell was also on the receiving end of the first one-way long-distance call, which was transmitted between Brantford and Paris, Ontario. In the months that followed Bell and Watson’s achievement, they continued to refine the instrument and eventually demonstrated it publicly at the Philadelphia Centennial Exhibition. Though his instrument had yet to transmit a human voice, on March 7, 1876, Bell received a patent for his telephone, which was described as an “apparatus for transmitting vocal or other sounds telegraphically.” Three days later, on March 10, Bell spoke through the instrument to Watson, using the now famous line, “Mr. The transmitter was capable of varying electronic currents, and the receiver could reproduce those variations in audible frequencies. In 1875, Bell spent several months creating a working transmitter and receiver with his laboratory assistant Thomas A. Known as “harmonic telegraphs,” these systems used reeds or tuning forks that responded to specific acoustic frequencies.īell became interested in how the human voice could be transmitted, and he formed an agreement with investor Gardiner Hubbard that allowed him to devote most of his time to developing the harmonic telegraph while also working on the concept of the telephone. While teaching, he spent time researching methods of transmitting several telegraph messages simultaneously over a single wire. Seeing the impact of communication and hearing loss on the lives of those around him, Bell was committed to developing improvements to the world of sound. In 1877, he married Mabel Hubbard, who had lost her hearing in childhood due to scarlet fever. While in the United States, Bell spent several years teaching at schools for the deaf. In 1870, his family immigrated to Canada, and one year later, Bell moved to Boston. His father and grandfather had been elocutionists who worked with the deaf, and his mother was almost fully deaf. Inspired to Inventīell was born in Edinburgh, Scotland, in 1847. Thanks to his contributions, communications continue to expand and improve across the globe, allowing people to stay connected from virtually anywhere. Most notably, Bell is credited for his invention of the telephone, which grew out of his research on the telegraph. National Inventors Hall of Fame ® (NIHF) Inductee Alexander Graham Bell is recognized for his innovations in telegraphy, or the practice of constructing communications systems for the transmission of information. One of history’s most well-known inventors drew on personal experience to develop improvements in communication. Inventors are constantly searching for solutions to the problems they face, often using personal experience as inspiration. Many great inventions are born out of the desire to fix or improve the challenges of daily life.
