Hedy Lamarr. Born in Austria, she fled and moved to the USA when Hitler took over Germany in 1933 and because she was of Jewish origins, Austria was becoming a hostile place to live also. Because of her beauty, she was able to resume her acting career in Hollywood but during World War 2, she also helped the war effort, and she invented the technology for radio frequency alternation, and this laid the foundation for WIFI and GPS later on.
