Hedy Lamarr

She married Friedrich Mandl, a wealthy merchant, in 1933 while she was still a teenager. Her husband was too controlling and thus she ended this marriage in 1937.

She was briefly married to screenwriter and producer, Gene Markey, from 1939 to 1941. She adopted a son during this marriage.

Her third marriage to actor John Loder, in 1943, produced two biological children. This marriage too ended in divorce in 1947.

She was born as Hedwig Eva Maria Kiesler on 9 November 1914, in Vienna, Austria-Hungary. She was the only child of Emil Kiesler, a successful bank director, and Gertrud "Trude" Kiesler, a pianist.

She was interested in acting from a young age and was discovered by the producer Max Reinhardt who brought her to Berlin. She received training in theater and returned to Vienna where she began to work in the film industry, starting out as a script girl before becoming an actress.

She appeared in Gustav Machatý's film, ‘Ecstasy’ in 1933 as a young married woman who becomes involved in a passionate extra-marital affair with a soldier. She stirred considerable controversy with this role and became notorious for appearing in the nude in some of the scenes.

At that time she was married to a controlling man from whom she escaped and fled to Paris. There she met MGM head Louis B. Mayer who offered her a movie contract in Hollywood. She adopted the screen name ‘Hedy Lamarr’ at his suggestion.

In 1938, she appeared in her first Hollywood movie, ‘Algiers’ opposite Charles Boyer. The movie became a sensation as the American audiences were captivated by Lamarr’s stunning beauty and striking onscreen persona.

She became one of the most successful actresses in Hollywood over the next few years and appeared alongside several of the leading men of that era. She acted in 18 films during the 1940s which include ‘Boom Town’ (1940) with Clark Gable and Spencer Tracy, ‘Tortilla Flat’ (1942), co-starring Tracy, and ‘Samson and Delilah’ (1949), opposite Victor Mature.

During the 1940s, Hedy Lamarr also became involved in scientific research and in collaboration with George Antheil, an avant garde composer, she co-created a frequency-hopping system for which the duo also received a patent.

As an actress, her most memorable role was in the movie ‘White Cargo’ (1942), which was based on a Broadway hit play by Leon Gordon. The film, in which she plays a beautiful seductress, was one of her biggest commercial hits.

Hedy Lamarr in collaboration with George Anthiel co-created a frequency-hopping system to help combat the Nazis in World War II. The duo’s invention, though not much recognized during their lifetimes, served as a basis for modern spread-spectrum communication technology, such as Bluetooth, COFDM, and CDMA.
