Home computing pioneer Sir Clive Sinclair dies aged 81

Creator of the landmark ZX Spectrum and the less commercially successful C5 died after a long illness

Sir Clive Sinclair, the inventor and entrepreneur who was instrumental in bringing home computers to the masses, has died at the age of 81.

His daughter, Belinda, said he died at home in London on Thursday morning after a long illness. Sinclair invented the pocket calculator but was best known for popularising the home computer, bringing it to British high-street stores at relatively affordable prices.
