Augustus Le Plongeon

Augustus Henry Julius Le Plongeon (May 4, 1826 - December 13, 1908) was a Jersey-born American medical doctor, photographer, traveller, amateur archaeologist, and antiquarian who devoted considerable attention and time to his study of the Maya civilization on the northern Yucatán Peninsula, producing many books and articles detailing his theories about the Mayans and what he perceived to be their links to other world cultures, including Egypt and Atlantis (which he asserted was called Mu).
