One of the most historically significant Twentieth Century science fiction series ever published is at last collected. A pioneer in pulp science fiction, Ray Cummings inspired an entirely-new fiction genre with his influential story originally published in 1919, The Girl in the Golden Atom, which introduced the world to a series of short stories and novels known as his "Matter, Space and Time" range. This suite of stories featured the Scientific Club: a group of New York-based socialites of revolving membership who either recounted these tales of fantastic science--or were directly involved in these tales which originally appeared in the top magazines of the 1920s: All Story Weekly, Argosy, Detective Story Magazine, Flynn's, and Science and Invention, among others. This collection assembles all of the Scientific Club stories, sourced directly from their original magazine appearances... most of which have never before been reprinted. In addition, this deluxe edition includes all of Cummings' Scientific Club stories which appeared exclusively in the United Kingdom. It also gathers the later Scientific Club stories from a brief revival in the mid-1930s. No stone has been left unturned for this edition: two hitherto-unknown Scientific Club stories were discovered, and these have been included, along with 26 other stories. And among the many bonus features is a rare, alternate, early version of one of the Scientific Club stories. Rounded out by vintage illustrations by Virgil Finlay, Frank R. Paul, Norman Saunders, Amos Sewell, Modest Stein, and Lawrence Sterne Stevens, and with an all-new introduction by Will Murray, The Complete Tales of the Scientific Club is a book one hundred years in the making.
