Jacques Blumenthal (1829 – 1908) was a German pianist and composer. Born in Hamburg, he began his musical studies at an early age, receiving instruction from Friedrich Wilhelm Grund, Carl Maria von Bocklet, and Simon Sechter. In 1846 he entered the Conservatoire de Paris, where he studied the piano under Henri Herz and Fromental Halévy. In 1848 Blumenthal settled in London, where he became the pianist to Queen Victoria. The position contributed to his demand as a teacher in London society, and he prospered greatly. Blumenthal also composed a number of works; his short piano pieces and songs achieved considerable popularity, though his efforts at larger pieces did not meet with success. He died at his home in Chelsea in May 1908.
