Rudolf Kálmán was born in Budapest in 1930 but emigrated to the United States in 1943 where he studied electrical engineering at the Massachusetts Institute of Technology. He received his doctoral degree at the Columbia University in New York City in 1957. His most famous scientific invention, the “Kálmán filter”, was used during the Apollo program as well as in the NASA Space Shuttle, in US Navy submarines, and in aerospace weapons, such as cruise missiles.

During his outstanding scientific career Rudolf Kálmán worked as a leading researcher in Baltimore and Zürich and also as a professor at Stanford University (1964-1971) and at the University of Florida (1971-1992). He was a member of the U.S. National Academy of Sciences, the American National Academy of Engineering.
