Sir Clive Sinclair, inventor behind Spectrum computer and C5, dies aged 81

Technology pioneer Sir Clive Sinclair has died at the age of 81, his family have confirmed.

The entrepreneur was most widely known for popularising the use of a home computer and was also the inventor of the pocket calculator.

His ZX Spectrum inspired future generations of video game developers, with many honing their skills on the computer, which was a competitor to the Commodore 64.

His daughter Belinda told The Guardian that he died at home in London on Thursday morning.

She told the newspaper: “He was a rather amazing person. Of course, he was so clever and he was always interested in everything. My daughter and her husband are engineers so he’d be chatting engineering with them.”

Sir Clive had considerably less success with his Sinclair C5 tricycle that he struggled to sell and the company that made them eventually went into liquidation.
