William Herschel's 40 foot (12 m) telescope. Scanned from Leisure Hour, Nov 2,1867, page 729.
Much astronomical work of the period becomes shadowed by one of the most dramatic scientific discoveries of the 18th century. On March 13, 1781, amateur astronomer William Herschel spotted a new planet with his powerful reflecting telescope. Initially identified as a comet, the celestial body later came to be accepted as a planet. Soon after, the planet was named Georgium Sidus by Herschel and was called Herschelium in France. The name Uranus, as proposed by Johann Bode, came into widespread usage after Herschel's death.
