Paul de Schlözer or Paweł Schlözer (1841 or 1842 – 1 July 1898) was a Polish pianist and teacher of German descent. He was possibly also a composer, but the only two works attributed to him may have been written by Polish composer Moritz Moszkowski.Very little is known about his life. He became the piano accompanist to Pablo de Sarasate and to his own brother, the violinist Teodor (Fyodor) de Schlözer. In 1879 he taught at the Institute of Music in Warsaw, where he succeeded Juliusz Janotha. Ignacy Jan Paderewski mentions him in his letters, sometimes by disparaging references such as "Mr. Paul" and "Pablito". Around 1892 he became a professor at the Moscow Conservatory, where his most important pupil was the music historian Leonid Sabaneyev. On 3 February 1894, he performed the Chopin Cello Sonata with the visiting Czech cellist Hanuš Wihan, at the Conservatory.His niece Tatiana Fyodorovna Schlözer became Alexander Scriabin’s second wife. His nephew, Tatiana’s brother, was the music critic Boris de Schlözer.
