Sound innovator Stefan Kudelski dies

Oscar winner invented Nagra, first portable professional recorder

Stefan Kudelski, inventor of the first portable professional recorder, the Nagra, and founder of the Kudelski Group, died Jan. 26 in Switzerland. He was 84.

“The Nagra recorder was the mainstay of production recording for over 50 years and revolutionized both production and post-production workflows,” said Cinema Audio Society president David E. Fluhr. “and the worldwide sound community mourns the passing of Stefan Kudelski.”

Kudelski received Oscars in 1965, 1977, 1978 and 1990 and Emmys in 1984 and 1986.

In 1983, Kudelski received the John Grierson International Gold Medal, joining luminaries of the Society of Motion Picture and Television Engineers that include Louis Lumiere, Thomas Edison, Lee de Forest, George Eastman, Walt Disney, Samuel Warner, Leon Gaumont, Ray Dolby and Vladimir Zworkyin.

A tribute to Kudelski will be held at the 49th annual CAS Awards on Feb. 16 at the Biltmore Hotel in downtown Los Angeles.
