#3: Hedy Lamarr
I’d like to think Hedy Lamarr belongs to a different generation of celebrities when the actors and actresses who populated our stages and screens weren’t trust-fund babies who got their first role at age five but hard-working folks who slaved away in order to make it to an audition.

That’s why it seems completely reasonable for an actress in the 1940s to also be a successful inventor. She was industrious from the very beginning, thinking up inventions in her spare time on set. The war merely provided a catalyst (as did her arms-dealing husband). Even wikipedia calls her an “actress and inventor”.
