Hans Lippershey also known as Johann Lippershey or Lipperhey. He was born in Wesel, in western Gemany, in 1570. And he died in September 1619, in Middelburg. He was a German-Dutch spectacle-maker. His name is commonly associated with the invention of the telescope because he was the first one who tried to obtain a patent for it. He is known for the earliest written record of a refracting telescope, a patent he filed in 1608.
Hans Lippershey invented the first telescope in 1608, in the Netherlands.
