Frédéric Chopin: Born March 1, 1810 (?)

ChopinFryderyk Franciszek Chopin…and his family held his date of birth to be 1 March 1810, yet the certificate of baptism signed in the parish church of Brochów is dated 22 February. That discrepancy has still not been entirely resolved, although today it is the date celebrated by Chopin and his family that is more often used. http://en.chopin.nifc.pl/chopin/life/biography/page/1

Arthur Rubinstein: Born January 28, 1887

Arthur Rubinstein made his first United States tour in 1906 when he was only 19 years old. He became one of the world’s foremost concert artists.

Rubinstein was born in an Lodz, Poland, on January 28, 1887. He made his first public performance at the age of seven. Four years later, the child prodigy was sent to Berlin to be presented to the great violinist, Joseph Joachim. Impressed with the boy’s amazing talent, Joachim offered to assume responsibility for Rubinstein’s cultural and musical education. At the age of thirteen, Rubinstein debuted formally in Berlin with the Berlin Philharmonic at a concert featuring the Mozart A major and Saint-Saens G minor concertos. In 1906, he made his American debut, performing with the Philadelphia Orchestra at Carnegie Hall. His success here initiated a tour of the United States that included over 40 concerts.
