Stookie Bill, c 1923.

This was a dummy head used by John Logie Baird (1888-1946) in his experimental television work. Baird began experimenting with imaging systems in the early 1920s. In 1924 he transmitted outline images over wires and by 1925 he was able to transmit recognisable human faces. In 1926 he started the world's first television station, which he named 2TV.
