"Like many women in the 1950s, Bette Nesmith Graham made a living as a secretary. The problem was that she wasn’t a good typist, and kept making mistakes. So she began experimenting with ways to cover up errors. She mixed ingredients such as white tempera water-based paint in her kitchen blender and painted over her mistakes with a thin paintbrush. She began marketing her typewriter correction fluid as "Mistake Out". The name was later changed to Liquid Paper. In 1979, she sold Liquid Paper to the Gillette Corporation for $47.50. Her son, Michael Nesmith, would also find fame as a member of the rock band The Monkees."
