HERSCHEL; Friedrich William; 1738-1822; GBR

Military musician, Herschel left Hanover for England in 1756. Installed in Bath, his interest for astronomy grew and was rising when his sister arrived en 1773. After having read some books, he went on to construct a telescope. With the experience gained, he built increasingly larger telescopes: 18-inch and then 48-inch. He selled some through entire Europe for kings and emperors as well as astronomers (BODE in Berlin, SCHROETER, PIAZZI and PONS). Herschel began his observations by measuring mountains on the Moon and then discovered Uranus in 1781 (and 2 satellites afterwards), as well as some satellites of Jupiter in 1789 and 434 doubles stars. He discovered about 2514 "nebulae" and published them in 3 separate lists. He also proposed the word "asteroid" to name the discoveries of PIAZZI and OLBERS.
