Hedy Lamarr wasn’t just a stunning Hollywood actress in the '30s and '40s—she was also a brilliant inventor who helped shape modern technology! During World War II in 1942, Hedy teamed up with composer George Antheil to invent a groundbreaking radio signaling device that could switch frequencies to prevent enemies from decoding secret messages. Though never used in war, this idea became the foundation for Wi-Fi, Bluetooth, and modern radio communication! It was only at the end of 20th century that Hedy was properly recognized, garnering awards right before her death in 2000 for her incredible inventions.
At SHARP, students use the radio function, sound, and Bluetooth capabilities in their coding projects with the Micro:bit. These wireless technologies are built on principles pioneered by Hedy Lamarr’s groundbreaking work in frequency-hopping spread spectrum. Without her contributions, modern wireless communication—including the tools our students use—would not exist. Thanks to innovators like Hedy, our students can explore coding, creativity, and invention, paving the way for future technological breakthroughs!
