Hedy Lamarr, often proclaimed “the most beautiful woman in the world.” The 26-yr-old Hedy Lamarr was doing well in Hollywood when, in September 1940, Nazi U-boats hunted down and sank a cruise ship trying to evacuate 90 British schoolchildren to Canada.

Seventy Seven of them drowned in the North Atlantic. Hedy Lamarr was a Jewish immigrant from Nazi-occupied Austria, and had made America her home since 1938 – she was absolutely outraged at this shocking act. She fought back by applying her engineering skills to development of a sonar sub-locator used in the Atlantic for the benefit of the Allies.The principles of her work are now incorporated into modern Wi-Fi, CDMA and Bluetooth technology, and this work led to her to be inducted into the National Inventors Hall of Fame in 2014

Later of course, she would became very famous following her portrayal of Delilah alongside Victor Mature in the 1949 film ‘Samson and Delilah’
