The first one to have made a reflector was an Italian monk, named Niccolo Zucchi, during the 1616's. But the reflector he had made had flaws, and he gave up the project. His concave mirror was of the wrong shape, and he couldn't view the images without blocking the mirror. About 54 years later, his invention was refined at the hands of Sir Isaac Newton, the same one who had discovered gravity. He fixed the monk's flaws, and the traditional two-mirrored reflecting telescope was named after him, called the Newtonian reflector.
