From an early age he was recognized as a prodigy, and after studying in Vienna with Karl Czerny and Simon Sechter he became a teacher at fourteen; by the age of eighteen he was a well-known virtuoso in Viennese music circles. Besides performing, he became a very influential piano teacher, first at the conservatory in St. Petersburg, which he co-founded, and subsequently in Vienna. His students included many of the most renowned pianists of their time, including Ignacy Paderewski, Artur Schnabel, Alexander Brailowsky, Ossip Gabrilowitsch, Mark Hambourg, and many others. Leszetycki was also a composer, having under his name over seventy piano pieces, two operas, several songs, and a one-movement piano concerto. He died in Dresden, Germany.
