Thomas Alva Edison
Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an inventor and merchant who developed a lot of devices that greatly influenced life in the 20th century. He was named by a journalist. “Sorcerer Master in Menlo Park”, he was one of the first inventors to apply the principles of mass production to the creative process, and thus could be considered to have created a public research lab. First career. Some inventions were attributed to him, although he was not the first person to have that idea, but after the first patent was changed it became his (the most famous is the light bulb, in fact is the work of many people inside his company). Edison is considered one of the most inventive inventors in history, and he holds 1,093 patents in the United States under his name, as well as patents in the United Kingdom, France, and Germany (totaling 1,500 in total). worldwide invention).
Thomas Edison and the phonograph
Not studying at school, Edison studied on his own books. Gradually, with the thought, explore, perform not pay attention to the empty theory, each step Edison conquered what the people at the time thought was impossible. His first invention was a dual telegraph capable of simultaneously broadcasting two messages. Soon after, he improved into a loader, downloaded and downloaded. The investment is sold to Western Union for $ 10,000.
Some time later, discouraged by the work of a telegraph, Edison went to New York, the first financial center of the time, hoping to earn more for his experiments. Here, he collaborated with several friends to set up a small company specializing in electricity and telegraphy. His second invention was to improve the multi-load telegraph into the Telegraph System to receive banking exchange news. The first machine gave him a large amount of money. The whole number of advances earned at this time, he poured all into his experiments later.
The first invention that made Edison famous was the phonograph in 1877. The public could not have imagined this invention and considered it a magic thing. Edison began to be called “Sorcerer in Menlo Park, New Jersey”, where he lived. His first phonograph recorded the sound on tin-lined poles for low sound quality and it destroyed the recording track when listening again so it could only be heard once. In the 1880s, a redesigned model used beeswax-coated cardboard posts made by Alexander Graham Bell, Chichester Bell, and Charles Tainter. This is one reason why Thomas Edison continues to work to create his own “Perfect Singing Machine”.
He also invented the electronic tally machine and applied for a patent, but was rejected.
