Sir Clive Marles Sinclair (born 30 July 1940) is an English entrepreneur and inventor, most commonly known for his work in consumer electronics in the late 1970s and early 1980s.

After spending several years as assistant editor of 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 into the production of home computers 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 recognised for its importance in the early days of the British home computer industry.

Sinclair Research also produced the TV80, a flatscreen portable mini television utilising an ingenious cathode ray tube however, LCD television technology was in advanced development and the Sinclair FTV1 (TV80) was a commercial flop, only 15,000 units being produced.

Knighted in 1983, Sinclair formed Sinclair Vehicles and released the Sinclair C5, a battery electric vehicle that was also a commercial failure. Since then Sinclair has concentrated on personal transport, including the A-bike, a folding bicycle for commuters that weighs 5.5 kilograms (12 lb) and folds down small enough to be carried on public transport.

Early life, family and education

Sinclair's father and grandfather were engineers; both had been apprentices at Vickers the shipbuilders. His grandfather George Sinclair was an innovative naval architect who got the paravane, a mine sweeping device, to work. George Sinclair's son, George William "Bill" Sinclair, wanted to take religious orders or become a journalist. His father suggested he train as an engineer first; Bill became a mechanical engineer and remained in the field. At the outbreak of World War II in 1939 he was running his own machine tools business in London, and later worked for the Ministry of Supply.[1]

Clive Sinclair was born to George Sinclair and Thora Edith Ella Marles in 1940 near Richmond, then in Surrey. He and his mother left London for safety to stay with an aunt in Devon, where they eventually travelled to Teignmouth. A telegram arrived shortly afterwards, bringing the news that their home in Richmond had been bombed. Sinclair's father found a house in Bracknell in Berkshire. His brother Iain was born in 1943 and his sister Fiona in 1947.[1]

At the age of 14, Sinclair designed a submarine. During holidays he could pursue his ideas and teach himself what he wanted to know. Sinclair had little interest in sports and found himself out of place at school. He preferred the company of adults, which he got only from his family.[2]

Sinclair attended Boxgrove Preparatory School, excelling in mathematics. By the time he was ten, his father had financial problems. He had branched out from machine tools and planned to import miniature tractors from the U.S.; he had to give up the business.[2] Because of his father's problems, Sinclair had to move school several times. After a time at Reading School, Sinclair took his O-levels at Highgate School in London in 1955 and A-levels in physics, pure maths, and applied maths at St. George's College, Weybridge.[3]

During his early years, Sinclair earned money mowing lawns and washing up, and earned 6d (old pence) more than permanent staff in a café. Later he went for holiday jobs at electronic companies. At Solatron he inquired about the possibility of electrically propelled personal vehicles. Sinclair applied for a holiday job at Mullard and took one of his circuit designs; he was rejected for precociousness.[citation needed] While still at school he wrote his first article for Practical Wireless.[3]

Sinclair did not want to go to university when he left school at the age of 18 and instead he sold miniature electronic kits by mail order to the hobby market.[4]
