Heinrich Gustavovich Neuhaus (Russian: Ге́нрих Густа́вович Нейга́уз, Genrikh Gustavovič Nejgauz; 12 April [O.S. 31 March] 1888 – 10 October 1964) was a Soviet pianist and pedagogue of German extraction. He taught at the Moscow Conservatory from 1922 to 1964. He was made a People's Artist of the RSFSR in 1956. His pedagogic book The Art of Piano Playing (1958) is regarded as one of the most authoritative and most widely used treatments on the subject. He died in Moscow in 1964.
He was born in Elisavetgrad (known since 2016 as Kropyvnytskyi), in present-day Ukraine. Although both his parents were piano teachers, he was largely self-taught. The biggest influences on his early artistic development came from his second cousin Karol Szymanowski (tutored by Heinrich's father, Gustav Neuhaus) and especially his uncle Felix Blumenfeld on his visits to his sisters' home. He also received some lessons from Aleksander Michałowski. In 1902 he gave a recital in Elisavetgrad with the 11-year-old Mischa Elman and in 1904 gave concerts in Dortmund, Bonn, Cologne and Berlin. Subsequently he studied with Leopold Godowsky in Berlin and from 1909 until the outbreak of World War I at his master classes in Vienna Academy of Music.
