George Antheil was a man who lived a long time ago and he really liked music. He was born in America but he moved to Europe when he was a young man to learn more about music. He learned how to play the piano and how to write music. He was a very good musician.
One day, when he was living in Paris, George Antheil met a woman named Hedy Kiesler. She was very smart and she also liked music. Hedy Kiesler was an actress and she was very interested in science and technology. She wanted to invent things that would help people.
George Antheil and Hedy Kiesler became very good friends and they started talking about different ideas. They wanted to create something that would help soldiers during the war. This was a long time ago when there was a big war going on in Europe.
They came up with an idea for something called a "frequency hopper". This was a machine that could send secret messages between soldiers without the enemy being able to listen in. The machine would change the frequency of the messages many times per second so that the enemy would not be able to understand what was being said.
George Antheil and Hedy Kiesler got a patent for their invention and they tried to sell it to the American Navy. The Navy thought the idea was very interesting but they did not use it during the war. Many years later, other people used the same idea to create something called Wi-Fi, which is what we use to connect to the Internet today.
So, George Antheil was a man who loved music and he made a machine with his friend Hedy Kiesler that helped create Wi-Fi.
