Harry Nyquist (1889–1976) was a Swedish-American physicist at Bell Labs. His early theoretical work on determining the bandwidth requirements for transmitting information set forth in this article laid the foundations for later advances by Claude Shannon. Shannon credits Nyquist (together with Hartley) as forming “the basis” of his theories. In this important article Nyquist isolated two key factors—signal shaping and choice of codes—as impacting the speed of data transmission.
