Influence of Her Father

Aside from enjoying appearing on stages, Hedy also developed an interest in technology and learned a few things from her father about technological inventions, especially during their walks and bonding sessions.

Start of Her Acting Career

Lamarr began her film career in Europe, where she starred in the controversial film Ecstasy. She married a wealthy arms dealer named Fritz Mandl, who tried to prevent her from acting. Lamarr fled from him and moved to Paris.

Invention of Frequency-Hopping Technology

Lamarr joined forces with composer George Antheil, and together, they devised a method of changing the frequency of radio signals at irregular intervals, making them harder to detect and block.

Patenting the “Secret Communication System”

They patented their invention in 1942 under the title “Secret Communication System.” However, the U.S. Navy didn’t adopt their idea until the 1950s, and they never received any compensation for their work.
