Sheldon Allan "Shel" Silverstein (September 25, 1930 – May 10, 1999) was an American writer known for his cartoons, songs, and children's books. He styled himself as Uncle Shelby in some works. His books have been translated into more than 30 languages and have sold more than 20 million copies. He was the recipient of two Grammy Awards, as well as Golden Globe Award and Academy Award nominations.
Silverstein believed that written works needed to be read on paper—the correct paper for the particular work. He usually would not allow his poems and stories to be published unless he could choose the type, size, shape, color, and quality of the paper. Being a book collector, he took seriously the feel of the paper, the look of the book, the fonts, and the binding. Most of his books did not have paperback editions because he did not want his work to be diminished in any way. Silverstein's estate continues to control copyright permissions on his work and has blocked the quotations of that work in at least one biographical treatment.
