Professor Emeritus Rudolf E. Kalman passed away in Gainesville, Florida, on July 2, 2016 at the age of 86 years.
A Hungarian-born American electrical engineer, mathematician, and inventor, he was most noted for his co-invention and development of the Kalman filter, a mathematical algorithm that is widely used in signal processing, control systems, and guidance, navigation and control. It removes “noise” from streams of data and increases accuracy. His method, a common discipline in the engineering and science communities, revolutionized modern automatic control and system theories.
