Who was Clive Sinclair ?

Sir Clive Marles Sinclair (July 30, 1940 – September 16, 2021) was an English entrepreneur and inventor, best known for his work on consumer electronics in the late 1970s and early 1980s.

After spending several years as an assistant editor for Instrument Practice, Sinclair founded Sinclair Radionics in 1961, where he produced the first slim-line electronic pocket calculator in 1972 (the Sinclair Executive). Sinclair later moved on to home computer production and produced the Sinclair ZX80, the UK’s first mass market home computer for less than £ 100, and later, with Sinclair Research, the ZX81 and ZX Spectrum; the latter is widely recognized by consumers and programmers for its importance in the early days of the British and European home computing industry in general. [1] In Eastern Europe, homemade ZX Spectrum clones were the only affordable computer equipment for a long period until the mid-1990s.

Sinclair Research also produced the TV80, a mini portable flat screen television that uses a cathode ray tube; however, LCD television technology was in advanced development and the Sinclair FTV1 (TV80) was a commercial failure, only 15,000 units were produced.

Knighted in 1983, Sinclair formed Sinclair Vehicles and released the Sinclair C5, a battery electric vehicle that was also a commercial failure. Sinclair then concentrated on personal transportation, including the A-bike, a folding commuter bike that weighs 5.7 kilograms (13 pounds) and folds small enough to be carried on public transportation.

London, England

Inventor Sir Clive Sinclair, who popularized the home computer and invented the pocket calculator, has died at his London home at age 81.

His daughter Belinda Sinclair said she passed away Thursday morning after having cancer for more than a decade.

Sir Clive’s products included the ZX series of computers and his ill-fated C5 electric vehicle.

He was still working on his inventions last week “because that’s what he loved to do,” Ms. Sinclair said.

“He was inventive and imaginative and for him it was exciting and an adventure, it was his passion,” she added.

Early life

Sinclair’s father and grandfather were engineers; they had both been apprentices at the Vickers boat builders. His grandfather George Sinclair was a naval architect who operated the paravane, a mine-clearing device. George Sinclair’s son, George William “Bill” Sinclair, wanted to take religious orders or become a journalist. His father suggested that he first train as an engineer; Bill became a mechanical engineer and stayed in the field. When World War II broke out in 1939, he ran his own machine tool business in London and later worked for the Ministry of Supply.


Its ZX Spectrum computers brought affordable personal computing to the masses, selling in the millions around the world.

However, in a 2013 BBC interview, Sir Clive revealed that, at the time, he was not using computers himself.

“I don’t like distraction,” he explained.

“If I had a computer, I would start to think that I could change this and that, and I don’t want to. My wife takes care of that very kindly.”


Unlike the ZX Spectrum, its attempt to launch an electric vehicle was unsuccessful.

The C5 was launched in 1985, and buyers were disappointed by its limited range, low speed, and inability to climb hills. It caused Sir Clive serious financial problems.

His daughter said, “I think sometimes it came too early [with his inventions].

“He was very good at imagining things that people might like or need, even though they didn’t know they wanted them.”

He was a devoted father and grandfather that his children Samuel, Henry and Florence will miss, said Ms. Sinclair.

“They were very close to him and took care of him over the years,” she said.

Sir Clive leaves behind three children, five grandchildren, and two great-grandchildren.
