Hans (Johann) Schläger (5 December 1820 – 17 May 1885) was an Austrian conductor and composer, important in the musical life of Salzburg in the 1860s. He was particularly involved in choral music.
From 1845 to 1847 he studied composition under Gottfried von Preyer at Vienna Conservatory, and later studied singing at the Akademie der Tonkunst in Vienna. From 1854 to 1861 he was director of the Wiener Männergesang-Verein ("Vienna Men's Choral Society"); as its director he won a prize at the Singing Festival in Nuremberg in 1861.[1][2]
In 1868 he married Countess Pauline von Oldershausen (born Countess von Zichy-Vásonykeő).[4]
He resigned from his offices and devoted himself to composition.[1][3] He was adviser to the publisher Breitkopf & Härtel on their complete edition of Mozart (now known as the Alte Mozart-Ausgabe).[1]
Compositions, some of which were printed, include operas (Hans Haidekukuk, Die Prophezeiung and Doctor und Friseur), songs, choral works, 2 symphonies and 3 string quartets.[1][3] His biographer in Biographisches Lexikon des Kaiserthums Oesterreich (1875) wrote: "Music critics praise in Schläger's compositions originality of invention, stylish portrayal of characters and action, and colourful instrumentation."[3]
