Sinclair, Clive

    Sir Clive Sinclair (1939- ) The British inventor who
   pioneered the home microcomputer market in the early 1980s,
   with the introduction of low-cost, easy to use, 8-bit
   computers produced by his company, Sinclair Research.

   Sir Clive also invented and produced a variety of electronic
   devices from the 1960s to 1990s, including pocket calculators
   (he marketed the first pocket calculator in the world),
   radios and televisions.  Perhaps he is most famous (or some
   might say notorious) for his range electric vehicles,
   especially the Sinclair C5, introduced in 1985.  He has been a
   member of MENSA, the high IQ society, since 1962.
