Joseph Anton Bruckner (1824 – 1896) was an Austrian composer and organist best known for his symphonies and sacred music. The symphonies are considered emblematic of the final stage of Austro-German Romanticism because of their rich harmonic language, strongly polyphonic character, and considerable length. Bruckner’s compositions helped to define contemporary musical radicalism, owing to their dissonances, unprepared modulations, and roving harmonies.

Unlike other musical radicals such as Richard Wagner and Hugo Wolf, Bruckner showed respect, even humility, before other famous musicians, Wagner in particular. This apparent dichotomy between Bruckner the man and Bruckner the composer hampers efforts to describe his life in a way that gives a straightforward context for his music. Hans von Bülow described him as “half genius, half simpleton”! Bruckner was critical of his own work and often reworked his compositions. There are several versions of many of his works.
