John Logie Baird (1888-1946), the television pioneer, watching a test transmission on his 30 line Model A 'televisor' television, at Long Acre in London, June 1931. This photograph was taken during preparations for the world's first television outside broadcast - the televising of the 1931 Epsom Derby. After a serious illness in 1922, Baird devoted himself to experimentation and developed a crude TV apparatus, able to transmit a picture and receive it over a range of a few feet. The first real demonstration was within two attic rooms in Soho, London, in early 1926, and by 1927 he managed to transmit pictures by telephone line from London to Glasgow.
