About Bette Nesmith Graham
Bette Nesmith Graham was an American inventor, entrepreneur, businesswoman, and philanthropist from the state of Texas. While working as a secretary in the 1950s, she developed the correction fluid known as Liquid Paper. Graham founded the Liquid Paper Company in 1958, built it into a multimillion-dollar business with international reach, and sold it to Gillette Corporation in 1979. She was the mother of musician Michael Nesmith. About a dozen colleagues asked McMurry for the product, so she created a label and the name "Mistake Out". By 1975, "Liquid Paper was producing 25 million bottles a year and holding a vast share of a multimillion-dollar market that had spawned several competitors, like Wite-Out".
