The invention of the telescope Historians are not absolutely sure who invented the telescope, but it is known that in 1608 a Dutch spectacle maker, Hans Lipperhey, announced a new lens-based seeing instrument that made distant objects appear much closer. This is the first evidence we have of the invention of the telescope, the first scientific instrument to extend one of the human senses. Source: www.rmg.co.uk/stories/topics/history-telescope

"For it is true that astronomy, from a popular standpoint, is handicapped by the inability of the average workman to own an expensive astronomical telescope. It is also true that if an amateur starts out to build a telescope just for fun he will find, before his labors are over, that he has become seriously interested in the wonderful mechanism of our universe. And finally, there is understandably the stimulus of being able to unlock the mysteries of the heavens by a tool fashioned by one's own hand." Russell W.
