Description

John Logie Baird presenting the transmitting portion of the original experimental Baird television apparatus to the Science Museum, September 1926. Baird (1888-1946) was a Scottish inventor. The transmitting portion, a large spinning cardboard disc containing 30 lenses in a spiral, was used to scan a puppet called Stooky Bill. As the disc rotated, each of the lens scanned a different part of the subject. This was first suggested by Paul Nipkow (1960-1940) in Berlin in 1884. During 1929-35 the BBC transmitted experimental Television using this system, and a year later the world's first regular high definition television service begun.
