Her stuck moment: As a bank secretary in the 1940s, Graham was frustrated by how hard it was to erase electric typewriter errors.
She strays from the usual: Graham gained fresh perspective at her second job, painting holiday windows at the bank. Painters paint over their mistakes, so she tried it on her typing errors.
Unstuck result: In 1956, Graham put the fluid on the market as “Mistake Out,” later changing it to “Liquid Paper.” In 1979, she sold her company for $47.5 million.
