Hedy Lamarr was so much more than a pretty face. In addition to being considered the most beautiful woman in cinema at the time of golden Hollywood, she was a brave fighter who hid a prodigious mind. Locked up by her first husband, Hedy took advantage of her atrocious captivity to continue her engineering studies that would culminate in a large number of inventions that would forever change the destiny of humanity. And it is that the great contribution of this incredible woman had nothing to do with her dazzling beauty, but with her ability to conceive a wireless communication system that is considered the forerunner of Wi-Fi, practically essential in our lives today.
