An article in today’s Washington Post looks at the mystery about where the information found in Martin Waldseemüller’s 1507 map — the first one to label the New World as “America” — came from, and interviews John Hessler, author of a recent book on the subject, The Naming of America. (An online discussion between Hessler and the writer of the article will take place tomorrow — Tuesday, November 18 — at 11:00 AM EST.)
