Briton who invented calculator dies at age 81

LONDON—Clive Sinclair, the British inventor who pioneered the pocket calculator and affordable home computers, reportedly died on Thursday at the age of 81. He passed away at his home in London after fighting cancer for more than a decade, UK media said. He was still working on inventions last week, his daughter Belinda Sinclair told the BBC. Clive Sinclair’s groundbreaking products included the first portable electronic calculator in 1972. The Sinclair ZX80 home computer launched in 1980 and sold for less than £100 at the time.
