Austrian composer, music publisher, and pianist best known for providing the simple waltz theme that inspired Ludwig van Beethoven's monumental 'Diabelli Variations'.Born near Salzburg, Diabelli trained as a priest before pursuing music. He moved to Vienna in 1803, establishing himself as a successful piano teacher and composer of light, accessible works. In 1818, he co-founded the publishing firm Cappi & Diabelli (later Diabelli & Co.), which became one of Vienna's leading music publishers, issuing early works by Franz Schubert and promoting Beethoven. While he composed masses, operettas, and numerous piano pieces, his lasting fame rests almost entirely on the waltz theme Beethoven transformed.

• Diabelli's original waltz theme was intended as part of a collaborative project: he invited 50 Austrian composers (including Schubert, Czerny, and the young Liszt) to each write one variation. Beethoven, initially dismissive, was later captivated by the theme's potential and composed not one, but 33 variations (Op. 120), creating one of the greatest piano masterpieces. This ironically overshadowed Diabelli's own contribution.
• His publishing house, Diabelli & Co., played a crucial role in music history. It published a vast amount of Schubert's work after his death, preserving his legacy. Diabelli also published works by Beethoven (including the Diabelli Variations themselves), Czerny, Hummel, and the young Johann Strauss I.
• Diabelli composed prolifically, particularly for the amateur market. His output includes masses, operettas, songs, and a huge quantity of piano music, especially sonatinas, dances, and didactic pieces, many of which remain valuable teaching repertoire.
• He died in Vienna on April 7, 1858. While a respected figure in Viennese musical life during his lifetime, his fame today is inextricably linked to Beethoven's genius response to his simple waltz.
