Unit 4: STEM Women Rock! (2nde)

Hedy Lamarr

We have learned about Hedy Lamarr who was a famous American woman, an actress in Hollywood, a scientist and an inventor. She was active in the 1940s. Google decided to honor her with a doodle because she had an extraordinary life. Indeed, she was not only a well-known actress, but also a renowned scientist who invented a system to prevent the Germans from spying the USA during WWII. She used Morse signals through radio waves to communicate from afar. Her discovery led to the invention of Wi-Fi. 

Her invention has a great impact on our daily lives. Indeed, if she had not invented this system, we would not be able to use wireless connection today.
