Thomas Alva Edison Thomas Alva Edison - physicist and prolific inventor who received almost no formal education, having been kicked out of school as a retard and tutored by his mother. At the age of 14, he was already an entrepreneur. He set up a laboratory in an abandoned wagon, as well as a printing press for his newspaper, which he mostly wrote himself. At the age of sixteen, he became a telegraph operator and began a career as an inventor and invented and patented an electrical apparatus for recording votes in elections. Later, he invented the paper tape "ticker", used to send stock market prices across the country. His more notable inventions include the carbon granule microphone, an improvement on Bell's telephone, the phonograph, and the electric light bulb. While working on the light bulb, he also discovered the "Edison effect", the fact that electric current flows from the heated fiber to the nearby electrode, but not in the opposite direction. Edison's influence on life in the 20th century was enormous. He was one of the first inventors to apply the principles of mass production, and he is considered to have created the first industrial research laboratory.
