Johann Georg Albrechtsberger (3 February 1736 – 7 March 1809) was an Austrian musician who was born at Klosterneuburg, near Vienna.
He originally studied music at Melk Abbey and philosophy at a Benedictine seminary in Vienna and became one of the most learned and skillful contrapuntists of his age. Albrechtsberger’s earliest classmates included Michael Haydn and Franz Joseph Aumann.
His fame as a theorist attracted to him in the Austrian capital a large number of pupils, some of whom afterwards became eminent musicians. Among these were Johann Nepomuk Hummel, Ignaz Moscheles, Josef Weigl (1766–1846), Ludwig-Wilhelm Tepper de Ferguson (1768-after 1824), Antonio Casimir Cartellieri, Ludwig van Beethoven, and Franz Xaver Wolfgang Mozart.
Albrechtsberger died in Vienna; his grave is in St. Marx cemetery.
