    • Her work was a forerunner to modern day Bluetooth technology used in mobile phones and Wi-Fi systems.
      • She never received any money for her invention that was largely ignored at the time

  • She was marketed as the most beautiful woman in the world by Hollywood film makers
    • But she lived an unhappy life as a movie actress beset by scandal, celebrity, sexism and depression.
