Composer Literature

[Polonaise]

Well, I researched Fryderyk Chopin, because I was interested to see if he wrote anything other than music (poetry, books, etc.) and I came across something that said that he indeed did write poetry as a boy, but it never became published as his music did. So I was wondering, does anyone know of a music composer who, as well, wrote literature as well? I would be interested in knowing who you may have found.
