Harold Stephen Black was an American electrical engineer who invented the negative feedback amplifier in 1927. This innovation revolutionized electronics by allowing for the linearization of nonlinear electronic devices like vacuum tubes and transistors. Despite initial instability concerns, Black’s work led to major advancements in amplifier design and expanded the applications of electronic devices. His influential paper on stabilized feedback amplifiers, published in 1934, cemented his reputation as a pioneering figure in the field.
