Louis Moreau Gottschalk (May 8, 1829 – December 18, 1869) was a New Orleans-born composer of Creole heritage. Here’s how the Wikipedia entry of his biography begins:
He had six brothers and sisters, five of whom were half-siblings by his father’s biracial mistress.[2] His family lived for a time in a tiny cottage at Royal and Esplanade in the Vieux Carré. Louis later moved in with relatives at 518 Conti Street; his maternal grandmother Bruslé and his nurse Sally were both Saint Dominican Creoles. He was therefore exposed to a variety of musical traditions, and played the piano from an early age. He was soon recognized as a prodigy by the New Orleans bourgeois establishment, making his informal public debut in 1840 at the new St. Charles Hotel.
This composition, “Le Bananier” (The Banana Tree) was based on a Creole folk melody.
