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.
One of the first forms of correction fluid was invented in 1956 by American secretary Bette Nesmith Graham, founder of Liquid Paper. 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. Tipp-Ex GmbH only started to produce white correction fluid in 1965 under the brand Tipp-Ex, but also as C-fluid.
When Nesmith was 13, his mother invented the typewriter correction fluid later known commercially as Liquid Paper. Over the next 25 years, she built the Liquid Paper Corporation into an international company, which she sold to Gillette in 1979 for $47.5 million.
Other work examined the problem of compressibility at high subsonic speeds, known as the Prandtl–Glauert correction. This became very useful during World War II as aircraft began approaching supersonic speeds for the first time. He also worked on meteorology, plasticity and structural mechanics.
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.
Its earliest form was invented in 1874 by Eugenio de Zuccato, a young Italian studying law in London, who called his device the Papyrograph. Zuccato's system involved writing on a sheet of varnished paper with caustic ink, which ate through the varnish and paper fibers, leaving holes where the writing had been.
Barometer. A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries .
In the 1950s and 1960s, correction fluid made its appearance, under brand names such as Liquid Paper, Wite-Out and Tipp-Ex; it was invented by Bette Nesmith Graham. Correction fluid was a kind of opaque, white, fast-drying paint that produced a fresh white surface onto which, when dry, a correction could be retyped.
