Jovan StosicAnton Grigorevich Rubinstein (Russian: Антон Григорьевич Рубинштейн, tr. Anton Grigorevich Rubinshteyn; November 28 [O.S. November 16] 1829 – November 20 [O.S. November 8] 1894) was a Russian pianist, composer and conductor who became a pivotal figure in Russian culture when he founded the Saint Petersburg Conservatory. He was the elder brother of Nikolai Rubinstein who founded the Moscow Conservatory.
As a pianist, Rubinstein ranks among the great 19th-century keyboard virtuosos. He became most famous for his series of historical recitals—seven enormous, consecutive concerts covering the history of piano music. Rubinstein played this series throughout Russia and Eastern Europe and in the United States when he toured there.
Although best remembered as a pianist and educator (most notably in the latter as the composition teacher of Tchaikovsky), Rubinstein was also a prolific composer throughout much of his life. He wrote 20 operas, the best known of which is The Demon. He composed a large number of other works, including five piano concertos, six symphonies and a large number of solo piano works along with a substantial output of works for chamber ensemble.
