A lifelong resident of Austria, Haydn spent much of his career as a court musician for the wealthy Esterházy family on their remote estate. Isolated from other composers and trends in music until the later part of his long life, he was, as he put it, "forced to become original". At the time of his death, he was one of the most celebrated composers in Europe.
Joseph Haydn was the brother of Michael Haydn, himself a highly regarded composer, and Johann Evangelist Haydn, a tenor. He was also a close friend of Wolfgang Amadeus Mozart and a teacher of Ludwig van Beethoven.
