Thomas Alva Edison was an Inventor in the late 1800s. He invented thousands of useful tools to use now, but the most important of all is the electric light bulb.
Thomas A. Edison was born in 1847 in Milan, Ohio. As a boy he hardly at all when to school, but this young boy was full of curiosity and bright ideas. He got his first job at the age of 12years. What his job was, was selling newspapers on a train to passengers. He also wrote his own journal on a secondhand printing press, in the luggage car. This first invention was followed by hundreds more during his long life.
Some of his inventions were an early form of a moving picture, a machine that counted electrical volts, and a method of propelling helicopters using explosives. In 1878-79 Thomas and Joseph of England invented the electric light bulb.
These two men had an electrical company called Electrical Light Company. They invented a light bulb that could screw into a socket.
Thomas Edison also invented an early phonograph. The sound it made was so weak that he had to use special earphones had to be used to hear the sound loud enough. He kept a bed in his lab in Menlo Park, New Jersey, so he could spend all of his time inventing. He became know as the “Wizard of Menlo Park.”
Thomas Edison was 21 years of age when, in 1808 he received his first patent, for an electric vote recorder. Before he was thirty, he had developed an astounding array of devices, including the mimeograph, the Dictaphone, improvements on the telegraph, and of the most important of all his inventions, the phonograph. He has now invented more than a thousand inventions. Thomas A. Edison, the principal of the light bulbs, was known long before a light bulb was created. The imperfect vacuum in the early bulbs meant that the filament quickly burned in the remaining air. Many people, including US inventors, searched for a practical solution. In 1879 using a new air pump, Edison produced a...
