He was credited with creating and disseminating designs for the first practical telescope. Crude 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 (beating Jacob Metius by a few weeks), 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.
