Niels Wilhelm Gade (22 February 1817 – 21 December 1890) was a Danish composer, conductor, violinist, organist and teacher. He is considered the most important Danish musician of his day.[1Gade was born in Copenhagen, the son of a joiner and instrument maker. He began his career as a violinist with the Royal Danish Orchestra, which premiered his concert overture Efterklange af Ossian ("Echoes of Ossian") in 1841. When his first symphony was turned down for performance in Copenhagen, he sent it to Felix Mendelssohn.
