I love things like this: read how 8 famous writers chose their pen names.
"Some pen names are fairly well-known for what they are. Most people know that Mark Twain was the alias of Samuel Langhorne Clemens. The outing of Richard Bachman as a pen name used by Stephen King was well-publicized and inspired King’s novel, The Dark Half. Some pen names you don’t see coming, though, and assume the name on the book cover is the real deal."
Can you guess who Ricardo Eliecer Neftalí Reyes Basoalto is? How about, Eric Arthur Blair? This nice piece from Mental_Floss.com gives you the answers. Read it here.
