Artur Schnabel (April 17, 1882 – August 15, 1951) was an Austrian classical pianist, who also composed and taught. Schnabel was known for his intellectual seriousness as a musician, avoiding pure technical bravura. Among the 20th century's most respected and most important pianists, his playing displayed marked vitality, profundity and spirituality in the Austro-German classics, particularly the works of Beethoven and Schubert. His performances of these compositions have often been hailed as models of interpretative penetration, and his best-known recordings are those of the Beethoven piano sonatas. Harold C. Schonberg referred to Schnabel as "the man who invented Beethoven".
