Donald Allen Wollheim 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.


In 1937, Wollheim founded the Fantasy Amateur Press Association. The first mailing was distributed in July of that year and included this statement from Wollheim: "There are many fans desiring to put out a voice who dare not, for fear of being obliged to keep it up, and for the worry and time taken by subscriptions and advertising. It is for them and for the fan who admits it is his hobby and not his business that we formed the FAPA."
