(William) Vincent Wallace (11 March 1812 – 12 October 1865) was an Irish composer and musician. In his day, he was famous on three continents as a double virtuoso on violin and piano. Nowadays, he is mainly remembered as an opera composer of note, with key works such as Maritana (1845) and Lurline (1847/60), but he also wrote a large amount of piano music (including some virtuoso pieces) that was much in vogue in the 19th century. His more modest output of songs and ballads, equally wide-ranging in style and difficulty, was also popular in his day, some numbers being associated with famous singers of the time.
