Invention
The Schmitt trigger was invented by US scientist Otto H. Schmitt in 1934 while he was still a graduate student, later described in his doctoral dissertation (1937) as a "thermionic trigger". It was a direct result of Schmitt's study of the neural impulse propagation in squid nerves.

Famous quotes containing the word invention:
“In all her products, Nature only develops her simplest germs. One would say that it was no great stretch of invention to create birds. The hawk which now takes his flight over the top of the wood was at first, perchance, only a leaf which fluttered in its aisles. From rustling leaves she came in the course of ages to the loftier flight and clear carol of the bird.”
—Henry David Thoreau (1817–1862)
“Heredity is a strong factor, even in architecture. Necessity first mothered invention. Now invention has little ones of her own, and they look just like grandma.”
—E.B. (Elwyn Brooks)
“A great man quotes bravely, and will not draw on his invention when his memory serves him with a word as good. What he quotes, he fills with his own voice and humour, and the whole cyclopedia of his table-talk is presently believed to be his own.”
—Ralph Waldo Emerson (1803–1882)
