Invention
Refractors were the earliest type of optical telescope. The first practical refracting telescopes appeared in the Netherlands about 1608, and were credited to three individuals, Hans Lippershey and Zacharias Janssen, spectacle-makers in Middelburg, and Jacob Metius of Alkmaar. Galileo Galilei, happening to be in Venice in about the month of May 1609, heard of the invention and constructed a version of his own. Galileo then communicated the details of his invention to the public, and presented the instrument itself to the Doge Leonardo Donato, sitting in full council.

Famous quotes containing the word invention:
“The public values the invention more than the inventor does. The inventor knows there is much more and better where this came from.”
—Ralph Waldo Emerson (1803–1882)
“Out of countless memories, invention selects a few that become “the story of my life.””
—Mason Cooley (b. 1927)
“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)
