# William Herschel (@william-herschel)

William Herschel was a German-born British musician and astronomer who discovered Uranus in 1781, constructed powerful reflecting telescopes, surveyed nebulae and double stars, and discovered infrared radiation.

His observing program depended deeply on Caroline Herschel’s recording, calculation, cataloging, and independent discoveries. Their surviving papers document a scientific partnership, not a solitary observer.
