Galileo Galilei didn't actually invent the telescope. A Dutchman, Hans Leppershey, invented 'a device used to hold two lenses apart that focused on refracting light through the lenses to make objects look closer' in 1608. He applied for a patent on it but it was declined because other scientists claimed to have made similar items. Galileo heard of this and decided to build his own, calling it a 'looking glass' that was based on Leppershey's work.
He made it in 1610, and demonstrated it in 1611.
Summer of 1609, first telescope by Galileo.
