Gerald Stillit information

Gerald Barry Stillit FCA (born 1938) is a British-born inventor, publisher and polyglot, who founded and was chairman of Stillit Books Ltd of Bond Street, his former educational publishing company. In 1963, Stillit invented an electronic corrector (Stillitron Teaching Aid) which was first applied as a teaching tool in conjunction with mathematics, science and language textbooks, used extensively throughout the British schooling system in the 1960s. This device was the first of its kind to combine circuit-board electronics with the ability to provide students with immediate positive feedback in monitoring answers to multiple choice questions. Subsequently, the electronic corrector was developed alongside a series of language courses which sold millions of copies worldwide throughout the 1970s and 1980s.
