- Karl Willy Wagner
Karl Willy Wagner (1883-1953) was a German pioneer in the theory of electronic filters. He is noted by
Hendrik Bode as being one of two Germans whose; [Bode, H W, "Network Analysis and Feedback Amplifier Design", Robert E Krieger Publishing, 1975.]The other German being referred to is
Wilhelm Cauer . Wagner was the second referee on Cauer's milestone 1926 thesis [Cauer, W, "Die Verwirklichung der Wechselstromwiderstände vorgeschriebener Frequenzabhängigkeit" ("The realisation of impedances of specified frequency dependence"), "Archiv für Elektrotechnic", vol 17, pp355-388, 1926.] 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).
