In the field of supernatural and fantastic literature, certain names come readily to mind "“ E. T. A. Hoffmann, Edgar Allan Poe, H. P. Lovecraft "“ but the name of Fitz-James O"™Brien has been unjustly overlooked and nearly forgotten since his premature death in 1862 during the American Civil War. "˜The Diamond Lens"™, O"™Brien"™s most famous short story, can be regarded as a forerunner of the science-fiction genre; "˜What Was It?"™ is alleged to have served as a model for H. G. Wells"™s The Invisible Man; and ''The Wondersmith"™ is a marvellous tale of Hoffmannesque invention. Taken together, O"™Brien"™s few surviving stories give him an important place in the development of American fiction and remain as fresh today as when they first written more than a hundred and fifty years ago.
