Frederick William Herschel was a Hanoverian-born British astronomer, technical expert, and composer. Herschel followed his father into the Military Band of Hanover, before migrating to Great Britain at the age of nineteen. He became famous for discovering the planet Uranus (along with two of its major moons, Titania and Oberon), the two moons of Saturn, and the existence of infrared radiation. He is also known for his musical compotions, which included twenty-four symphonies.
