The history of the telescope can be traced to before the invention of the earliest known telescope, which appeared in 1608 in the Netherlands, when a patent was submitted by Hans Lippershey, an eyeglass maker. Although Lippershey did not receive his patent, news of the invention soon spread across Europe. The design of these early refracting ...
Hans Lipperhey[a] (c. 1570 – buried 29 September 1619), also known as Johann Lippershey or simply Lippershey, [b] was a German - Dutch spectacle-maker. He is commonly associated with the invention of the telescope, because he was the first one who tried to obtain a patent for it. [1] It is, however, unclear if he was the first one to build a ...

In early 1609, he bought a "Dutch trunke" (telescope), invented in 1608, and his observations were among the first uses of a telescope for astronomy. Harriot is now credited as the first astronomer to draw an astronomical object after viewing it through a telescope: he drew a map of the Moon on 5 August 1609 [O.S. 26 July 1609], preceding ...
