Heddy Lamarr, beautiful and bright. Was co-inventor of the earliest known form of the telecommunications method known as "frequency hopping" frequencies and was intended to make radio-guided torpedoes harder for enemies to detect or to jam.
Heddy Lamar. She was Jewish living in a Nazi occupied Austria. She was married to a Weapons Manufacturer and she learned a lot. She divorced her husband, left Germany for America and renewed her acting career in Hollywood. In her spare time, she developed a highly specialized frequency code that could keep torpedo guidance systems from getting jammed. It was only in the late 1990's that many a cell phone manufacturer realized that Heddy owned patents of the frequency skipping technology.
