Karl Willy Wagner (22 February 1883 – 4 September 1953) was a German pioneer in the theory of electronic filters. He is noted by Hendrik Bode as being one of two Germans whose;^[1]

. . . important contributions were slow to diffuse outside Germany because of the accidental intervention of World Wars I and II.

The other German being referred to is Wilhelm Cauer. Wagner was the second referee on Cauer's milestone 1926 thesis^[2] but Wagner fell out with Cauer in 1942 after he refused to support Wagner's research proposals with the German Society of Electrical Engineers (Verband der Elektrotechnik - the VDE).^[3]

Wagner was removed from office in 1936 because he refused to dismiss his Jewish employees.
