We're saddened to announce that CISE Professor Emeritus Gerhard X. Ritter, Ph.D., passed away this spring at the age of 89. Ritter had a long and distinguished career at the University of Florida, joining first the Department of Mathematics in 1971, then the emerging Department of Computer and Information Science in 1986, later renamed CISE. Ritter served as CISE department chair from 1998 to 2008.
“Gerhard helped steer the department through many challenging times,” remarked former CISE chair Patrick Traynor, Ph.D. “We are all the beneficiaries of a life dedicated to academic and community service whether or not we had the pleasure of knowing him personally.”
Ritter was perhaps best known for developing image algebra, a mathematical formalism that unifies linear and nonlinear mathematics in the image domain, supporting rigorous algorithm development, analysis and testing for image- and signal-based applications.
