William Wallace Cook was born in Marshall, Michigan, in 1867. He was the author of a memoir, The Fiction Factory, as well as dozens of Westerns and science-fiction novels, many of which were adapted into films. He was nicknamed “the man who deforested Canada” for the volume of stories he fed into the pulp-magazine mill. He spent five years composing Plotto before finally publishing it in 1928. Cook died in his hometown of Marshall in 1933.
