Leopold Godowsky (born February 13, 1870, Soshly, near Vilnius, Lithuania, Russian Empire—died November 21, 1938, New York, New York, U.S.) was a renowned Russian-born American virtuoso pianist and composer, known for his exceptional piano technique.
Godowsky entered the Berlin High School for Music at age 14; soon thereafter he went to the United States, where he spent most of the remainder of his life. His first American concert was in 1884; by 1890 he was teaching at the New York College of Music. He became a U.S. citizen in 1891. Godowsky taught later in Philadelphia and Chicago and in Vienna from 1909 to 1914. He pursued an international career until 1930, when a stroke ended his playing.
As a performer, Godowsky had a very advanced technique and a scholarly approach to the classics. Among his more than 400 original compositions and ornate transcriptions of older vocal and instrumental works are many that exploited his formidable dexterity but at the same time remain musically conservative. Most notable is his Triakontameron (1920), a cycle of 30 pieces. Rarely played since his death, his compositions are said to have influenced Maurice Ravel and the Russian composer Sergey Prokofiev.
