Abstract: Papers of Peter Lyon, a freelance writer of books, articles, and radio scripts. Drafts, correspondence, research files, reviews, and advertising for four books written or ghosted by Lyon comprise the bulk of the collection. Of these, material on To Hell in a Day Coach: An Exasperated Look at American Railroads (1968) and Success Story: The Life and Times of S. S. McClure (1963) are the most complete. In addition, there are published works on alcoholism and Coney Island and unpublished manuscripts about Isaac Singer and confidence men of the past, some biographical information, materials on Lyon's other two books, Eisenhower: Portrait of a Hero and The Wild, Wild, West, and sound recordings of interviews for book projects.
