Biography:

Sheldon Allan Silverstein (September 25, 1930 – May 10, 1999) was an American writer, poet, cartoonist, songwriter, and playwright. Born and raised in Chicago, Illinois, Silverstein briefly attended university before being drafted into the United States Army. Though perhaps best known for his children's books, Silverstein did not limit his audience to children. During his rise to prominence in the 1950s, his illustrations were published in various newspapers and magazines, notably the adult-oriented Playboy.
