Anton Diabelli (1781-1858) was an Austrian music publisher, editor, and composer who made significant contributions to music. In his early life, he was trained to enter the priesthood and sang in the boys' choir at Salzburg Cathedral. He moved to Vienna in 1803 to teach piano and guitar and worked as a proofreader for a music publisher. In 1817, he started a music publishing business and became known for arranging popular pieces that could be played by amateurs at home. Diabelli recognized Franz Schubert's potential and became the first to publish his work with Erlkönig in 1821. The most famous work Diabelli is known for is the waltz on which Beethoven wrote his set of thirty-three Diabelli Variations.
