Franz Joseph Haydn (1732–1809) was an Austrian composer, widely regarded as the “Father of the Symphony” and “Father of the String Quartet.” A central figure of the Classical era, he shaped musical form and style with innovation, wit, and expressive clarity. Haydn spent much of his career as court composer for the wealthy Esterházy family, producing operas, chamber works, and orchestral masterpieces. His influence deeply inspired Mozart and Beethoven, securing his legacy as one of Classical music’s great pioneers.
