Haydn was the composer who worked for the Esterhazy family.

Explanation:

Franz Haydn was one of the most important composers of the classical period. He personifies the so-called "Viennese classicism" alongside Wolfgang Amadeus Mozart and Ludwig van Beethoven. He is also regarded as one of the most important and influential authors in the history of Western classical music with a career spanning from the end of Baroque to the beginnings of Classicism.

He was the brother of fellow composer Michael Haydn, Mozart's colleague in Salzburg, and tenor Johann Haydn. Having spent most of his life in Austria, Haydn spent most of his career as a court musician for the rich Eszterhazy family.
