Home Computing Pioneer Sir Clive Sinclair Dies Aged 81

Sir Clive Sinclair, the inventor and entrepreneur who popularized the home computer and invented the pocket calculator, has died at home in London on Thursday at the age of 81.

Belinda Sinclair, Sir Clive’s daughter, confirmed his passing away after battling cancer for more than a decade.

Sir Clive’s products transformed home computing in this country when he launched his ZX81 and the later ZX Spectrum computers to the masses, selling in their millions across the world.

The computers, which were relatively cheap and easy to understand, kickstarted a boom in home programming and gaming.

Sinclair became the first company in the world to sell more than a million computers. This success made Sir Clive’s surname a household word and spawned an entire industry of magazines, games designers, and software and hardware developers.

“He was inventive and imaginative and for him it was exciting and an adventure, it was his passion,” said Ms. Sinclair. She also shared that her father was still working on his inventions last week “because that was what he loved doing”.
