He was 83 years of age. His professional work is renowned for its diversity, embracing the fields of speech processing, room acoustics, computer art, and number theory.

In his youth his father, a mining engineer, and his mother encouraged an early interest in the beauty and utility of mathematics. He was a leading student in his secondary schooling, but still not above enjoying practical jokes on colleagues and friends. Like many science-oriented young people of the time, he was attracted to radio technology. He built short-wave receivers and transmitters and, despite government restrictions, surreptitiously listened to broadcasts from the BBC (British Broadcasting Corporation). He never considered himself a legitimate “radio amateur” (“ham“) because of the difficulty of obtaining a government license and the (not unusual) additional obstacle of Morse code.
