Hans Wilhelm Schüessler has made substantial and long-lasting contributions to the theory, design and implementation of digital filters. He has shaped the research community immeasurably, particularly in Europe, where his vision has helped to expand signal processing research.

Among the first to use computers to simulate digital filters in the 1950s, Professor Schüessler made connections between signal processing and computing that helped lead signal processing from the analog to the digital domain. In the decades since, his research and teaching have seen breakthroughs in finite and infinite impulse response filters, digital filter implementation, sampling rates, quantization effects and more.

A professor at the University of Erlangen-Nuremberg, Germany since 1966, he has supervised nearly 50 Ph.D. candidates and taught courses at Cornell University, the Massachusetts Institute of Technology, Cambridge University, the University of Aachen, Karlsruhe University and Rice University. His research has focused on the design of pulseforming analog networks, digital filter synthesis and implementation, mobile communications and more. His work has been published in 90 technical papers and four books, including the first digital signal processing textbook published in German. He chaired Germany's first signal processing conference in 1973.

A recipient of the IEEE Acoustics, Speech and Signal Processing Society Award and an IEEE Centennial Medal, Professor Schüessler has been elected a member of the Bavarian Academy of Sciences and the Senate of the Deutsche Forschungsgemeinschaft. He has received numerous other honors including the Karl-Kupfmuller Award of the German Informationstechnische.
