Clive Sinclair

Sir Clive Marles Sinclair (born July 30, 1940) was a well-known British entrepreneur and inventor of the world's first 'slim-line' electronic pocket calculator in 1972 (Sinclair Executive) and the ZX80, ZX81 and ZX Spectrum computers in the late 1970s and early 1980s, amongst many other things. The ZX80 was the UK's first mass market home computer to be sold for under £100. Sinclair has been fascinated by electronics and miniaturization since his teenage years. In 1961 he founded Sinclair Radionics Ltd after spending several years as assistant editor for Practical Wireless and Instrument Practice to raise funds.

In later years Sinclair became a keen poker player. He appeared in the first three seasons of the Late Night Poker television series. He won the first season final of the Celebrity Poker Club spin-off, defeating Keith Allen. His most recent invention was the A-bike, a folding bicycle aimed towards commuters that weighs 5.5 kg (12 lbs) and folds to a very small size for easier carrying on public transport.
