Hans Lippershay (1570–1619)
Born 1570 CE, died 1619 CE.
Hans Lipperhey (c. 1570 – buried 29 September 1619), also known as Johann Lippershey or simply Lippershey, 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. It is, however, unclear if he was the first one to build a telescope.
