Born in Germany as Friedrich Wilhelm Herschel, it was only at the age of 30 that he discovered what his true passion was. One night, while observing the night sky with his sister Caroline, he discovered Uranus and several moons around other gas giants. While he was alive, he compiled a catalog of 2,500 celestial objects still used in society today. In his early life he mainly studied music with his sister. Her sister Caroline was the first woman to discover a comet and the first woman to obtain a paid scientific position and receive an honorary membership of the Royal Society. William Herschel will invent the theory of the evolution of stars. The early years of William Herschel William's father was an army musician. Following his father's profession, he played for the Hanover Guards. When the French took control of Hanover in 1757, he fled to England where he earned a living by copying music. He began improvising and began teaching music and eventually became a composer. In 1766 he was appointed organist of Beth Chapel. His curiosity for music leads him to read Harmonics by Robert Smith. After finding Smith's book interesting, he read A Complete System of Opticks, which introduced him to telescope building. Herschel told himself that he would not study the Sun and Moon like all the other astronomers did. Instead he thought of trying to search for different celestial bodies. The problem was that for this job he would need huge lenses, far more than he could afford at a reasonable price, so he decided to sculpt them himself. They were ground from metal disks of copper, tin and antimony in various proportions. His attempts, however, seemed futile, in h......middle of paper......attracted many visitors. Even princes and dukes came to visit his precious telescope. While living in Slough, Herschel discovered four moons, two orbiting Saturn and two orbiting Uranus. The Herschel telescope also showed 75 million stars that could not be seen before. ConclusionWilliam Herschel is still known today for his telescopes sold all over the world. He took something no one else would do and did what he was passionate about. Today he is credited with the discovery of Uranus and 4 moons, two orbiting Saturn and two orbiting Uranus. With the help of his sister and brother he managed to discover 2000 celestial bodies in the sky. Herschel was able to see 75 million stars that were not visible with any other telescope at the time. He was able to entertain princesses and dukes with his enormous 6 meter high telescope.
