Harold Stephen Black
Harold Stephen Black (born April 14, 1898 in Leominster , Massachusetts , † December 11, 1983 ) was an American electronics engineer.
Black is known as the inventor of the negative feedback amplifier . The work that led to the invention took place around 1930 in the laboratories of the Western Electric Company in the USA ( Bell Labs ). The principle of negative feedback was of paramount importance in the development of high quality telephone amplifiers. In addition, it forms the basis for almost all amplifiers used in practice today. Black received US Patent 2102671 for this invention in 1937.
Similar work also took place in Great Britain ( Paul GAH Voigt , British patent 231972) and in the Netherlands at Philips ( Bernard Tellegen , British patent 323823) during the same period . It is therefore controversial who may be considered the first inventor of the negative feedback amplifier.
