Sven Berglund
Sven Oscar Fredrik Archadiuson Berglund (born July 20, 1881 in Stockholm , Sweden , † in May 1937 in Berlin ) was a Swedish inventor and film pioneer.
Life
His parents were the colonels in fortifications Arcadius Berglund and Maria Zachrisson.
Berglund organized the first public screening of lip-synchronous sound film using the optical sound system on February 17, 1921 in Stockholm. He was an electrical engineer and also worked in Germany, in Laubegast, where he tried out his multiple double-point method. With his so-called comb diaphragm he produced 22 parallel double points in the tone writing, with which he had good photographic results. The sound quality was limited by the microphone , amplifier and speakers . There was a collaboration with Heinrich Ernemann AG , Dresden, with a contract dated May 24, 1922.
He made preliminary experiments with circular photo plates on which he exposed a double-pointed sound track in a spiral.
