Death of Calculator and Low-Cost Computers Inventor

British media reported on Thursday the death of British inventor Clive Sinclair, who created the portable calculator and low-cost home computers, at the age of 81. Sinclair passed away at his home in London after a battle with cancer for more than 10 years. Sinclair was working on new innovations last week, "because that was what fascinated him," according to his daughter in an interview with the BBC. She added: "He was an innovator and a creator. It was an exciting adventure for him. That was his passion," as reported by AFP. Among Sinclair's most notable inventions was the portable electronic calculator in 1972 and the "Sinclair ZX80" computer launched in 1980, which sold for around £100 at that time and contributed to popularizing computing among households in Britain and beyond.
