On January 23, 1926, John Logie Baird (of Scotland) gave the world's first public demonstration of a mechanical television apparatus to approximately 40 members of the Royal Institution at his laboratory on Frith Street. These were images of living human faces, not outlines or silhouettes, with complete tonal gradations of light and shade.
They first developed the Kinetophonograph (or Kinetophone), a precursor of the 1891 Kinetoscope (see below), that synchronized film projection with sound from a phonograph record. The projector was connected to the phonograph with a pulley system, but it didn't work very well and was difficult to synchronize. Although Edison is often credited with the development of early motion picture cameras and projectors, it was Dickson, in November 1890, who devised a crude camera that could photograph motion pictures - called a Kinetograph. This was one of the major reasons for the emergence of motion pictures in the 1890s.
