A Nipkow disk (sometimes Anglicized as Nipkov disk; patented in 1884), also known as scanning disk, is a mechanical, geometrically operating image scanning device, invented by Paul Gottlieb Nipkow. This scanning disk was a fundamental component in mechanical television through the 1920s.
Perhaps the main problem that Nipkow had with his scanning disc is that it is suggested that he never actually made one himself. Although he patented the idea in 1876, it is known that Nipkow never made practical use of the disc. It garnered such little interest that he allowed the patent to lapse twenty years later. John Logie Baird used the idea of the disc in the early 1920s to create the world's first working television. He used one disc for the image capture with a second disc for the display. Baird's challenge was to make sure the discs were rotating at the same speed and always staying at the same angle as each other. This problem was one of control rather than one of building the disc.

Many websites say that Charles Jenkins improved Paul Nipkow's spinning disk idea, and that he was the first American to do it.
Paul Gottlieb Nipkow died on August 24, 1940 at the age of 80.
Paul Gottlieb Nipkow was born on August 22, 1860 and died on August 24, 1940. Paul Gottlieb Nipkow would have been 80 years old at the time of death or 154 years old today.
Paul Nipkow invented an electromechanical television on December 24, 1883, and a patent on it was granted in 1885. It was further developed in England during the period around 1920, and the first broadcast television pictures displayed publicly in England in 1925 used his system. It was not as practical as the electronic scanning used today, however, and went out of use.
