She was a great actress but she was also an inventor and very intelligent. Some say her inventions lead to what we now call the “cell phone” or as the Europeans call them mobile phones.

Sorry you have that wrong, it wasn’t Gene Tierney, it was Hedy Lamarr who also invented as a hobby, notably something called ‘Frequency-hopping spread spectrum’ which today is used in Bluetooth apparently :))x
