I’ll soon be seeing Bombshell: The Hedy Lamarr Story, directed by Alexandra Dean, at the Jewish Film Festival. The festival programme says: Known for her striking looks and electric onscreen persona, Lamarr’s fans never knew she possessed such a beautiful mind. An Austrian Jewish émigré who acted by day and drew mechanical and electronic inventions by night, Lamarr came up with a secret communication system to help the Allies to beat the Nazis. Bombshell is for lovers of history, film and science. But locating the truth about her life was tricky. All the facts below come from Encyclopaedia of World Biography.
Hedwig Kiesler (1913–2000) was born in Vienna. Her parents were Jewish and cultivated; her father Emil Kiesler was a Bank of Vienna director and her mother Gertrud Lichtwitz a concert pianist from Budapest. Hedwig attended schools in Vienna then was sent to a Swiss finishing school.
After an unsuccessful audition with her acting teacher and stage director, Max Reinhardt, Hedwig moved into films. Her screen career began in 1930 with two Austrian films.

Hedy Lamarr and Clark Gable
Comrade X, 1940
She had several other small German-language roles, but it took controversy for Hedwig to be famous. In 1932 she made the film Ecstasy in Czechoslovakia, released in 1933. The film told of a young woman whose husband was impotent, causing her to seek a younger man. Two scenes were responsible for the film's notoriety and bans: a] Hedwig ran nude through a sunlit forest and b] a sex scene in which she experienced an intense orgasm.
Ecstasy attracted the attention of millionaire Austrian arms dealer Fritz Mandl, whom teenage Hedwig met in Dec 1933 and then married. Mandl had converted from Judaism to Catholicism in order to be able to do business with Germany's fascist regime, and Lamarr also converted from Judaism to Catholicism in 1933. Apparently Mandl tried to buy and destroy every outstanding copy of the film Ecstasy. Whether out of revulsion to her husband's politics or not, Hedwig packed a case with jewellery, drugged her maid and fled to Paris, London and New York in 1937.
Hedwig began negotiating with producer Louis B Mayer of Metro-Goldwyn-Mayer, who wanted new exotic European talent. Hedwig had refused Mayer's dismal contract offer in London, but by the time the ship docked in New York she had a handsome MGM contract and the brand new name of Hedy Lamarr. Mayer called her The Most Beautiful Woman in the World.
Lamarr's first American film was Algiers (1938) opposite French actor Charles Boyer. A successful launch for her American career, this film was followed by two flops, Lady of the Tropics (1939) and I Take This Woman (1940), co-starring Spencer Tracy. The actress's fortunes improved in 1940 with Boom Town starring Clark Gable, and Comrade X, an anti-Communist romance.
During WW2 Lamarr was an American sex symbol and star with Come Live with Me (1941), Ziegfeld Girl (1941), The Heavenly Body and the steamy White Cargo (both 1943), in which Lamarr played a mixed-race prostitute on an African rubber plantation. In 1943 Lamarr wanted the Casablanca role that eventually went to Swedish actress Ingrid Bergman.
Lamarr also appeared in celebrity gossip columns. She dated silent comedian Charlie Chaplin in 1941, and had flings with Burgess Meredith. Lamarr married producer Gene Markey in 1939, then divorced. Then she was married to English actor John Loder and had children. Later Lamarr was married three more times.

Hedy Lamarr and Victor Mature
Samson and Delilah, 1949
Modernist American composer George Antheil also played an important role in Hedy's life. Antheil was as well-connected as Lamarr; he met & in 1925 married Hungarian Boski Markus, niece of Austrian playwright Arthur Schnitzler.
Lamarr knew maths very well and had cleverly picked up practical munitions-engineering knowledge from Mandl. In 1940 she “solved” the problem of controlling a radio-guided torpedo. Electronic data broadcast on a specific frequency could easily be jammed by enemy transmitters, so Lamarr suggested rapid changes in the broadcast frequency. Antheil, who had experimented with electronic musical instruments, devised a punch-card-like device that could synchronise a transmitter and receiver.
The pair were jointly awarded a patent for their important discovery. But credit did not help the frequency-hopping idea; it was never applied by the military during WW2. The real payoff of frequency-hopping came only decades later, when it became integral to the operation of cellular telephones and Blue-tooth systems that enabled computers to communicate with peripheral devices. Too late for Lamarr and Antheil's patent.
Experiment Perilous (1944) was a great film. As was the Cecil B DeMille film Samson and Delilah (1949), with Victor Mature and Lamarr as the stars. The film combined a Biblical evangelical Christian moralism combined with hot sex!
Lamarr made several films in the 1950s, outside the Hollywood system. In the Italian-made feature The Loves of Three Queens (1954) she played Helen of Troy, and then Joan of Arc in The Story of Mankind (1958). But her heyday was past. In 1950 she auctioned off her possessions and retired from films.

In 1967 she published an autobiography, Ecstasy and Me: My Life as a Woman, but sued her ghost writers, claiming that the book was scandalous. She complained that she’d had a $7 million income but was now subsisting on a grotty pension. More litigation followed in 1974.
Lamarr was reclusive in her last years. The story of her radio transmission invention became widely publicised and she received an Electronic Frontier Foundation Pioneer Award in 1997. She died in Jan 2000 and was posthumously inducted into the National Inventors Hall of Fame in 2014.

Now my own questions. Undoubtedly Hedwig fell for Fritz Mandl’s charming personality, and was very impressed with his business acumen. But if Mandl's ties to Mussolini and Hitler were very close, how did Hedy’s Jewish parents allow their teenage daughter to marry him? And if Mandl’s own parents were Jewish, how did Hitler agree to buy the Nazis’ munitions from him? How did Hedy keep her Jewishness a total secret throughout her American life? Why was it only after her death that her children learned they were Jewish.
Why did Mussolini and Hitler attend lavish parties at the Mandl home during their marriage? If one of Mandl's favourite topics at these gatherings was the technology surrounding radio-controlled missiles and torpedoes, did the American government acknowledge Hedy’s military knowledge and want to exploit it? If Lamarr was involved in a system that would allow American torpedoes and guided bombs to always reach their Nazi targets, were the Germans interested in how much knowledge she took with her to the USA after 1937? And in how much expertise she was developing with George Antheil in the USA?
