Corle, Helen Freeman (Mrs. Edwin). "Notes on the work of Marcel Duchamp." Typescript. corrected. 51 pages, 1949-1951

This series is comprised of typescripts and proofs of scholarly essays and creative writings about Duchamp and his work, as well as a small amount of correspondence with Michel Carrouges, Helen Freeman Corle, Jean Jacques Mayoux, and other authors who sent their writings to Duchamp for his review and comment. Of particular note is the draft and translation of a letter Duchamp sent to Jean Jacques Mayoux supporting his critique of Michel Carrouges's "Les Machines celibataires." The series includes many published and unpublished essays written by friends and personal acquaintances of Duchamp, including Bill Copley, Helen Freeman Corle, Richard Hamilton, Walter Hopps, Frederick Kiesler, Gertrude Stein, Henri Pierre Roche, and Beatrice Wood.
