The product most people know as Tipp-Ex–style correction fluid was first invented as “Liquid Paper” by Bette Nesmith Graham , an American secretary and single mother from Texas, in the early 1950s. Tipp-Ex itself later became a German brand of correction products that built on this original idea.

Quick Scoop

  • The first modern correction fluid was invented in 1951 by Bette Nesmith Graham, who originally called it “Mistake Out” before it became Liquid Paper.
  • Tipp-Ex arrived later, in the 1960s, as a company and brand producing correction paper and then white correction fluid, popular especially in Europe.
  • So when people ask “who invented Tipp-Ex,” the underlying correction-fluid concept traces back to Graham’s Liquid Paper, not to a single Tipp-Ex-branded inventor.

Who Was Bette Nesmith Graham?

  • Bette Nesmith Graham was born in 1924 in Texas and worked as a secretary in Dallas in the 1950s, where her struggle with typing accuracy pushed her to experiment with a paper-colored paint to cover errors.
  • Mixing batches in her kitchen and bottling them like nail polish, she turned this into a business called the Mistake Out Company in the mid‑1950s, later rebranding the product as Liquid Paper and growing it into a multimillion‑dollar firm.

How Tipp-Ex Fits In

  • Tipp-Ex began as a German company that first developed correction paper; this work by Wolfgang Dabisch formed the starting point of the Tipp-Ex brand.
  • In 1965 the company launched the correction fluid that many people now casually call “Tipp-Ex,” but this came after Graham’s earlier invention of correction fluid in the United States.

In everyday use, “Tipp-Ex” became a generic word for white correction fluid, but the original idea and first commercial correction fluid came from Bette Nesmith Graham’s Liquid Paper.

TL;DR: The idea and first product of white correction fluid were invented by Bette Nesmith Graham (Liquid Paper), and the later Tipp-Ex brand built its own correction products on that foundation.
