The German organist and composer, Alfred Sittard, studied in Cologne under Friedrich Wilhelm Franke and became organist at Dresden Kreuzkirche in 1903, then in 1912 organist at the Michaeliskirche in Hamburg. In 1925 he became professor of organ studies at Universität der Künste in Berlin, where he died in 1942.
In his lifetime Alfred Sittard was considered one of the foremost organ virtuosos in Germany. Due to his influence through his teaching post in Berlin, he is a direct connection to the Berlin Organ School of the late 19th century and early 20th century among others like Max Reger and Karl Straube.
