Baird (1888-1946) demonstrating colour television to the press - including the sixth Marquess of Donegal, a journalist for the Sunday Despatch - in the lounge of his home at Crescent Wood Road, Sydenham in South London. 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 had managed to transmit pictures by telephone line from London to Glasgow.
