New Grove (Chopin, Fryderyk Franciszek (Frédéric François); b. ?Mar. 1, 1810, Żelazowa Wola, near Warsaw, d. Oct. 17, 1849, Paris; Polish composer; "The exact date of Chopin's birth is unknown. The traditional date, 1 March 1809, conflicts with Chopin's own belief that it was 1 March 1810. His baptismal certificate, discovered nearly 50 years after his death, states that he was born on 22 February 1810 and baptized on 23 April. It is now believed that a mistake of exactly one week was made when his birth was recorded in the register and that it was actually on 1 March 1810; this date is now the accepted one.")
