Robert Lester Stallman was an American literary critic, English professor and science fiction writer, author of the Book of the Beast trilogy.
[6] He worked as a professor of English at Western Michigan University in Kalamazoo, Michigan,[1] and was an authority on William Morris, as witness his doctoral thesis The Quest of William Morris (Eugene, Oregon: University of Oregon Press, 1966).
[1][8] Stallman's literary reputation is founded on his Book of the Beast trilogy, written late in life and published in part posthumously.
According to Peter Nicholls, the work is "an engrossing series" of "complex, sensitively written Fabulations, fitting between the generic borders of sf and Horror, and update the myth of the Werewolf with [an] sf premise."
He finds the final volume "awkwardly structured," however, judging it "needed a auctorial revision which it could not be given" due to Stallman's premature death.
