Invention of the Telescope
1608 · Early Modern
On October 2, 1608, Hans Lippershey, a German-Dutch spectacle maker from Middelburg, filed the first patent application for a refracting telescope with the States General of the Netherlands. His design featured a convex objective lens and a concave eyepiece lens in a tube, magnifying objects three times. Competing claims from Jacob Metius and Zacharias Janssen prevented any patent from being granted. In 1609, Galileo Galilei heard of the invention, built his own improved version with 20x magnification, and became the first to use it for systematic astronomical observations, revolutionizing our understanding of the cosmos.
