In 1926, the West End of London offered a dazzling range of evening entertainment. Choices included watching Fred Astaire and his sister Adele on stage at the old Empire theatre in Lady, Be Good!, or experiencing The Big Parade silent movie at the Tivoli on the Strand with a full live orchestra. But on a damp Tuesday evening 100 years ago, around 40 members of the Royal Institution – one of the UK’s most influential science research and education charities – chose instead to visit a makeshift laboratory on an upper floor at 22 Frith Street in Soho. Reportedly all attired in evening dress, they were responding to an invitation from the then little-known Scottish inventor John Logie Baird. The event became a landmark moment in television history. Baird successfully demonstrated an experimental prototype that could augment broadcast radio with live moving pictures. It was the world’s first demonstration of a mechanical television system able to show human faces. At the time, Baird called the display a “televisor”. John Logie Baird’s 1926 Televisor machine.
