Harold Stephen Black
From Wikipedia, the free encyclopedia
Harold Stephen Black (1898-1983) was an electrical engineer who revolutionized the field of applied electronics by inventing the negative feedback amplifier in 1927. He graduated from Worcester Polytechnic Institute in 1921. After his graduation, he went on to work in Bell Labs. To some, his invention is considered the most important breakthrough of the century in the field of electronics, since it has a wide area of application.
Black's 1953 book Modulation Theory was the source of the terms Nyquist rate and Nyquist interval, but he did not apply Nyquist's or Shannon's name to the sampling theorem as was done later by others, possibly over-interpreting Black's description of "the sampling principle".
