Donald Allen Wollheim (October 1, 1914 – November 2, 1990) was a science fiction writer, editor, publisher and fan. He published his own works under pseudonyms, including David Grinnell. A member of the Futurians, he was one of the leading influences on the development of science fiction and science fiction fandom in the 20th century United States. Wollheim's first story, "The Man from Ariel," was published in the January 1934 issue of Wonder Stories when Wollheim was nineteen. Wollheim was not paid for the story and when he began to look into the situation, he learned that many other authors had not been paid for their work, publishing his.
