Wilhelm Cauer (June 24, 1900 - April 22, 1945) was a German mathematician and scientist. He is most noted for his work on the analysis and synthesis of electronic filters and his work marked the beginning of the field of network synthesis. Prior to his work, electronic filter design was an art, requiring specialized knowledge and intuition. Cauer placed the field on a firm mathematical footing, providing a theoretical basis for the rational design of electronic filters. Wikipedia
