Hardcover. Zustand: Very Good. First Edition. Diagrams and figures, some folding; Large 8vo 9" - 10" tall; 128 pages; [SIGNED] 1931 Self-published by the author. Soundly bound in original black cloth, front board stamped in gilt with circular and square design and bold titling; gilt lettering at spine dulled and almost illegible. A key work of early 20th-century mathematical crank literature Heisel's privately printed "solution" to the classical problem of squaring the circle, offered here "beyond refutation. " Often cited in literature on pseudoscience and mathematical fallacies, including Martin Gardner's Fads and Fallacies in the Name of Science. This copy inscribed by the author on the front free endpaper: "To my dear niece, Mrs. A. J. Lyons [? ] from Carl Theodore Heisel, April 16th 1931." Notably accompanied by a manuscript letter from a recent prior owner seeking a mathematician's opinion on the validity of Heisel's work the owner proposed to use it in a middle-school math class. Also laid in is a photocopy of Charles Hadlock's article "Field Theory and its Classical Problems" presumably provided in response, as an implicit refutation. Binding sound; cloth with light shelf wear and corner rubbing, mild surface spotting to boards; gilt on front board bright but much dulled at spine. Contents clean and fresh. Heavily illustrated throughout with geometric figures, including numerous fold-out diagrams. A scarce signed copy of this celebrated American mathematical curiosity, with interesting provenance.
