Heinrich Fleischer (1912–2006) was an organist from Leipzig, Germany. He fought in World War II, in which he lost one finger on his left hand and another half finger. After the war, Fleischer re-taught himself to play the organ with his remaining fingers. He went on to become an organist at Valparaiso University, the University of Chicago, and the University of Minnesota. A student of Karl Straube, Max Reger's preferred performer for his works, Fleischer was a member of the late romantic school of organ playing. Many of his students have become great performers and teachers worldwide.[1]
