Hans Lippershey (1570 – September 1619), also known as Johann Lippershey or Lippershey, was a German-Dutch lensmaker, generally credited as being the inventor of the telescope.
He was born in Wesel, in western Germany. He settled in Middelburg in the Netherlands in 1594, married the same year, and became a citizen in 1602. He remained in Middelburg until his death.
He has been credited with creating and disseminating designs for the first practical telescope. Some telescopes and spyglasses may have been created much earlier, but Lippershey is believed to be the first to apply for a patent for his design, a few weeks before Jacob Metius, and making it available for general use in 1608. He failed to receive a patent but was handsomely rewarded by the Dutch government for copies of his design. The "Dutch perspective glass", the telescope that Lippershey invented, could only magnify thrice.
Lippershey's application for a patent was mentioned at the end of a diplomatic report on an embassy to Holland from the Kingdom of Siam sent by the Siamese king Ekathotsarot: Ambassades du Roy de Siam envoyé à l'Excellence du Prince Maurice, arrivé à La Haye le 10 Septemb. 1608 (Embassy of the King of Siam sent to his Excellency Prince Maurice, arrived on September 10, 1608). This report was issued in October 1608 and distributed across Europe, leading to experiments by other scientists, such as the Italian Paolo Sarpi, who received the report in November, the Englishman Thomas Harriot, who was using a six-powered telescope by the summer of 1609, and Galileo Galilei, who soon improved the device.[1]
One story behind the creation of the telescope states that two children were playing with lenses in the Lippershey's shop. The children discovered that images were clearer when seen through two lenses, one in front of the other. Lippershey was inspired by this and created a device very similar to today's telescope.
The lunar crater Lippershey and the minor planet 31338 Lipperhey are named after him.
