Ferdinand Joseph LaMothe (later Morton; c. September 20, 1890 – July 10, 1941), known professionally as Jelly Roll Morton, was an American ragtime and jazz pianist, bandleader, and composer.[1] Morton was jazz's first arranger, proving that a genre rooted in improvisation could retain its essential characteristics when notated.[2] His composition "Jelly Roll Blues", published in 1915, was one of the first published jazz compositions.
