Hedy Lamarr was a famous movie star, but she was also a brilliant inventor with a secret superbrain! When she wasn’t acting on the big screen, she loved to experiment and solve tricky puzzles. During a big war, she wanted to help keep secret messages safe from enemies. She invented a clever system that made radio signals hop around so nobody else could listen in!
Her amazing idea was called “frequency hopping,” and it changed the world of technology forever. Today, we use her incredible invention to help make Wi-Fi and Bluetooth work! So the next time you watch a video on a tablet or connect a wireless controller, remember to thank the glamorous and super smart Hedy Lamarr!
