William Herschel

William Herschel was a German-born musician who became the most prolific observer of his age, building the largest telescopes in the world. In 1781 he discovered Uranus — the first planet found since antiquity — doubling the size of the known Solar System, and he later discovered infrared light and mapped the structure of the Milky Way.
