Andrew Booth was one of the UK's early computing pioneers but who has been widely neglected in histories of UK computers. Working at Birkbeck College in London he built relay and electronic computers from 1946 onwards. He pioneered the use of rotating storage devices, building what is claimed to be the world's first computer to use a drum. He devised the Booth multiplier which is widely used in modern chips to this day. His hardware design was used by the UK's best selling computer in the late 1950s, the ICT 1200 series. Full details.
