Hans Lippershey, a Dutch eyeglass maker, made the first widely distributed telescope, and applied for the first telescope patent in 1608. The telescope was reinvented in Holland in 1608, and during the early part of the following year a report of the instrument reached Galileo in Italy. He experimented with different metals and polishing methods and made his first reflecting telescope in 1668. If inventing means being first to publish an effective design for a reflecting telescope then the inventor is Marin Mersenne (1636) or Bonaventura Cavalieri (1632). These distort under their… Many people think that the 16th-century inventor Leonard Digges created both the reflecting and refracting telescopes. The invention of the reflector telescope stretches back to Isaac Newton in the 17th Century. The largest refracting telescope (one that use lenses to gather and focus light) opened at Yerkes Observatory in Williams Bay, Wisconsin, in 1897. Newton invented the reflecting telescope which is a a great advance over the refracting telescope. In 1668, Isaac Newton invented it while solving the problem of chromatic aberrations in a refracting telescope. His earliest instrument was simply two lenses held in place so that an observer could look through them to distant objects. This means a greater amount of light . The new design used mirrors instead of lenses. Telescope History.
