Hedy Lamarr (born in 1914 in Vienna as Hedwig Eva Maria Kiesler, died 2000 in Florida) was given her first leading role in only her third film (“You don't need money”, with Hans Moser and Heinz Rühmann). However, it was a Czechoslovak-Austrian production entitled “Ecstasy” that led to a downright scandal in 1933, The cause of this was not only a 10 minute naked scene.After a varied life – Hedy Lamarr married a total of six times – she was finally discovered by Louis B. Mayer, who recruited her to the famous American film company Metro-Goldwyn-Mayer. She rapidly became a star and a fashion icon of the late 1930s.Alongside her career as an actress, however, Hedy Lamarr was also an inventor. Thus together with the composer George Antheil she developed, 'almost incidentally' while synchronising a piece of music, a radio-based remote control device for torpedoes, patented in 1942, which used automatically changing frequencies to protect it from interference. Although this invention was never used for military purposes, the patent is still used every day in modern communications technology in Bluetooth connections and in GSM technology.
