Of course a woman is behind some of the great inventions of our time.
Bette Nesmith Graham for instance.
She invented Liquid Paper, originally called "mistake out".
For 17 years she sold it from her kitchen-garage until in 1979 when she sold it to Gillette for 47.5 million dollars.
Did you recognize the name Nesmith? Bette was mother to Michael.

Bette left half her estate to Michael when she passed in 1980 so we have her to thank in part for the popularity today of music video. Michael invested his inheritance in Pacific Arts Studio, a forerunner in the production of video music.
Mother's of Invention indeed.
