Bette Nesmith Graham (March 23, 1924 – May 12, 1980) was an American typist, commercial artist, and the inventor of the correction fluid Liquid Paper. She was the mother of musician and producer Michael Nesmith of The Monkees. [1]
One of the first forms of correction fluid was invented in 1956 by American secretary Bette Nesmith Graham, founder of Liquid Paper. [1] With the advent of colored paper stocks for office use, manufacturers began producing their fluids in various matching colors, particularly reds, blues and yellows.
Product history. Liquid Paper. In 1956, Bette Nesmith Graham (mother of future Monkees guitarist Michael Nesmith) invented the first correction fluid in her kitchen. Working as a typist, she used to make many mistakes and always strove for a way to correct them.
Earlier, in 1951, [citation needed] Bette Nesmith Graham invented the first correction fluid in her kitchen and began marketing the product in 1956 as Mistake Out. [4] Tipp-Ex GmbH only started to produce white correction fluid in 1965 under the brand Tipp-Ex, but also as C-fluid .
Soon after the filing of the patent, in 1959, German entrepreneur Otto Wilhelm Carls from Frankfurt founded the company Tipp-Ex GmbH & Co. Kg and Tipp-Ex was registered as a trademark in 1987. [2] The Tipp-Ex name was used to distribute correction paper, and later correction tape and correction fluid worldwide.
Johanknecht enlisted the help of his associate George Kloosterhouse, a basement waterproofer who experimented with chemicals, and together they developed their own correction fluid, introduced as "Wite-Out WO-1 Erasing Liquid". In 1971, they incorporated as Wite-Out Products, Inc.

Correction tape. Correction tape is an alternative to correction fluid used to correct mistakes during typing, or, in some forms, handwriting. One side of the tape, which is placed against the area to cover, is coated in a white, opaque masking material. Pressure applied to the other side of the tape transfers this material to the paper.
Pioneers of fluid mechanics. Archimedes. Evangelista Torricelli. Blaise Pascal. Daniel Bernoulli. The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history.
t. e. The Navier–Stokes equations ( / nævˈjeɪ stoʊks / nav-YAY STOHKS) are partial differential equations which describe the motion of viscous fluid substances. They were named after French engineer and physicist Claude-Louis Navier and the Irish physicist and mathematician George Gabriel Stokes.
