Hello there, let me introduce you to an amazing woman who was both a glamorous movie star and a brilliant inventor Hedy Lemar. Yes, you heard that right she was a scientist and a Hollywood superstar. He was born in 1914 in Vienna in Austria. she loves solving puzzles and learn how things worked even as a little girl. But when she grew up, people noticed she was very beautiful and became a famous actress. She starred in lots of movies in the 1930s and 1940s. But he wasn't just about the Spotlight she loves science and inventing things. During World War II she wanted to help stop enemy ships so she worked with a friend George and Phil to create a special invention called frequency hopping. This invention made it hard for enemies to block or hack signals sent between radios. It was a really smart idea and later became important for technology that we used today like Wi-Fi and Bluetooth can you imagine that the same idea he came up with helps power the Internet on the tablet or computer? You are on. Even though people didn't recognise a genius at first today we celebrate had Mark as both a film star and a science hero she showed the world that you could be creative and smart at the same time so next time you connect to Wi-Fi, remember Hedy Lamar, the actress who changed the world of her ideas.
