Alfred Bingham recommends several books about his father’s work and the archeological exploration of South America. Of Hiram Bingham’s own writings, Lost City of the Incas (1948) presents his final story about Machu Picchu, thirty years later. It has been reissued in hardcover by Greenwood Press and in paperback by Atheneum. His Machu Picchu, a Citadel of the Incas (1930) is available in a lavishly illustrated edition from Hacker Art Books. John Hemming’s Conquest of the Incas (Harcourt Brace Jovanovich, 1973) is a fine history that includes an evaluation of Bingham’s work. In Antisuyo (Simon and Schuster, 1970), Gene Savoy, a later explorer, tells of retracing Bingham’s steps and finding other “lost cities.” A Search for the Apex of America , by Annie Smith Peck (1911), is the book that irritated Hiram Bingham.
