Explanation

Bette Nesmith Graham invented Liquid Paper (white-out) in 1951 while working as a secretary. She created the correction fluid using tempera paint to cover typing mistakes, and initially called it 'Mistake Out.' Her son Michael Nesmith later became famous as a member of The Monkees rock band. The product revolutionized office work and was eventually sold to Gillette for $47.5 million in 1979.
