In the 1870s, there were several scientist and inventors whom worked on photoelectric devices that turned light into an electric signal. In 1876 a German technician/inventor named Paul Nipkow had patented a rotating disc that could be used to capture and display an image using electricity. John Baird based his technology on Paul Nipkow's scanning disk idea and later developments in electronics. Although Nipkow had the patent, he never developed a use for the system, so the disc and the patent expired about twenty years later. No one was fully successful until 1925 when a Scottish man from England by the name of John Logie Baird and an American man named Clarence W. Hansell patented the idea of using different types of transparent rods to transmit images for television. Baird was...
