Thomas Alva Edison

           Thomas A. Edison was probably the greatest inventor in history, although he only went to public school for three months. Edison's first invention was the stock ticker, which prints a record of the purchase and sale of stock. The stock ticker made him a nice profit of $40,000. Some of his other inventions include the first successful motion picture device, the carbon transmitter which helped pave the way for the modern phone, the mimeograph machine(which was basically an old copy machine), the phonograph, which is a record player (also his favorite invention), and his invention we cannot do without, the electric light bulb.
