Georg Martin Adolf von Henselt (9 May 1814 – 10 October 1889) was a German composer and virtuoso pianist.
Henselt was born at Schwabach, in Bavaria. At the age of three he began to learn the violin, and at five the piano under Josephe von Flad (1778–1843). His concert debut was at the Odeon in Munich, where he played the opening Allegro to one of Mozart's C major concertos, a free fantasy with variations on a theme from Weber's Der Freischütz, and a rondo by Kalkbrenner. Later that year, he went to Vienna, where, besides studying composition under Simon Sechter (the later teacher of Anton Bruckner), he was successful as a concert pianist
Despite his relatively long life, Henselt ceased nearly all composition by the age of thirty, for reasons that are unclear. Chronic stage fright, bordering on paranoia, caused him to withdraw from concert appearances by age thirty-three.
He was considered to be one of the greatest virtuosos of his time.
