• Resumen

  • William Herschel (Fig. 1) is rightfully known as one of the greatest astronomers of all time. Born in Hanover (in modern Germany) in 1738, Herschel immigrated to England in 1757 and began a successful career as a professional musician. Later in life Herschel developed a strong interest in astronomy. He began making his own reflecting telescopes in 1774, and soon his telescopes were recognized as the finest in the world. It was through one of his homemade telescopes, a Newtonian reflector with a focal length of seven feet and an aperture of 6.2 inches, that Herschel first spotted the planet Uranus in 1781. The discovery of a new planet catapulted Herschel to fame and secured him a position as personal astronomer to King George III.
