Arthur Machen
Around 1890 Machen began to publish in literary magazines, writing stories influenced by the works of Robert Louis Stevenson, some of which used gothic or fantastic themes. This led to his first major success, "The Great God Pan". It was published in 1894 by John Lane in the noted Keynotes Series, which was part of the growing aesthetic movement of the time. Machen's story was widely denounced for its sexual and horrific content and consequently sold well, going into a second edition.
Norman Maclean
He spent the last years of his life attempting to write a non-fiction account of the 1949 Mann Gulch Forest Fire. The manuscript was published posthumously as "Young Men and Fire" and won the National Book Critics Circle Award in 1992. In 2008, The University of Chicago Press published a new compendium of unpublished and some previously published works, "The Norman Maclean Reader." The book included parts of a never-finished book about George Armstrong Custer and the Battle of the Little Big Horn that Maclean worked on from 1959 to 1963. Publishers Weekly gave the book a respectful review in Summer 2008, remarking, "Readers of the two earlier books will find, as Weltzien [Alan Weltzien, the book's editor] phrases it, 'new biographical insights into one of the most remarkable and unexpected careers in American letters.'"
