Biography

Sir Clive Marles Sinclair (30 July 1940 – 16 September 2021) was an English entrepreneur and inventor best known for popularizing affordable home computers and consumer electronics.

Early Life & Career

  • Self-Taught Innovator: Born in Richmond, Surrey, he was a largely self-taught autodidact who developed a deep passion for electronics as a teenager.
  • Electronics Journalist: Before founding his first business, he worked as a writer and assistant editor for radio and electronics magazines.

Major Inventions & Milestones

  • Pocket Calculators: In 1972, he launched the Sinclair Executive, the world’s first slim-line electronic pocket calculator.
  • Home Computers: He revolutionized the UK and European tech market by releasing low-cost personal computers, including the ZX80 (the UK’s first sub-£100 mass-market computer) in 1980, the ZX81, and the massively popular color-display ZX Spectrum in 1982.
  • Electric Vehicles: In 1985, he launched the Sinclair C5, a battery-electric tricycle that became a commercial failure and caused severe financial strain.
  • Later Projects: In his later years, he focused on personal transit, developing the lightweight folding A-bike and electric bicycle accessories.
