Hedy Lamarr was an actress and inventor known for her beauty and brains. She appeared in more than 30 films in Hollywood, including "Algiers" (1938), "Boom Town" (1940), and "Come Live with Me" (1941), and she is considered one of the most glamorous and talented actresses of the golden age of Hollywood.

But Lamarr was not just an actress; she was also a brilliant inventor. In the early 1940s, she and composer George Antheil developed a secret communication system that was intended to help the US military during World War II. The system, called "frequency hopping," used a piano roll to control the frequency of radio signals, allowing them to jump from one frequency to another in a random pattern that was difficult to detect or jam.

This technology was groundbreaking at the time and laid the foundation for modern wireless communication, including Bluetooth and WiFi. Lamarr and Antheil received a patent for their invention in 1941, but it was not used by the military until the 1960s when it was implemented in naval ships during the Cuban Missile Crisis.
Lamarr's work on frequency hopping was not widely known until the late 1990s when it was rediscovered and recognized for its importance. In 1997, she and Antheil were posthumously inducted into the National Inventors Hall of Fame, and in 2014, Lamarr was named one of the "Top 100 Women in STEM" by the STEMconnector organization.

Despite her many achievements, Lamarr's life was not always easy. She faced numerous challenges and setbacks, including a difficult childhood, a tumultuous personal life, and a lack of recognition and support for her inventions. She also struggled with depression and addiction, and she died in 2000 at the age of 85.
