Who was S. W. Erdnase?

S. W. Erdnase is the pen name on The Expert at the Card Table, a 1902 book on card table cheating and card magic that has never gone out of print. Nobody knows for certain who wrote it. The best-known theories point to a card cheat named Milton Franklin Andrews, a mining engineer named Wilbur Edgerton Sanders and a Chicago printer named Edward Gallaway, but none of them has been proven.

What is The Expert at the Card Table?

It’s a book about handling a deck of cards so well that nobody can tell you’re doing anything at all. It was published in Chicago in 1902, paid for by its own author and printed by James McKinney & Co. The title page of later printings calls it a treatise on “the science and art of manipulating cards.”

The book has two halves. The first, “Card Table Artifice,” covers the methods of the professional card cheat: blind shuffles and cuts, bottom and second dealing, palming and shifts. The second, “Legerdemain,” turns the same skills toward entertainment, with sleights and a set of card tricks for the conjuror.

Erdnase draws a clear line between the two worlds. He writes that at the card table “the entire conduct must be in perfect harmony with the usual procedure of the game,” which is a big part of why his techniques look so natural. That idea of a move that looks like nothing still shapes how card magicians think today.

Why does a 1902 book still matter?

Most magic books from 1902 are read today as history. This one is still read as a manual. The card magician Dai Vernon is credited with spreading its reputation among professional magicians, and he quoted from it for decades. The book has since been translated into several languages and issued in many special editions.

The preface is part of the legend. Instead of a moral excuse for teaching cheating methods, the author says plainly that if the book sells, “it will accomplish the primary motive of the author, as he needs the money.” For a book whose author vanished, it’s a strangely personal line.

Why is the author such a mystery?

“S. W. Erdnase” is almost certainly not a real name. Spelled backwards it reads “E. S. Andrews,” and the letters also rearrange into “W. E. Sanders.” Both clues have sent researchers hunting for more than a century.

There was no second book, no interview and no public appearance. The copyright was never renewed. The one person known to have met the author is the illustrator, credited on the title page as M. D. Smith. Martin Gardner tracked Marshall D. Smith down in Chicago in 1946, 44 years after that single meeting. Smith remembered meeting the author in a hotel room and described a short, well-spoken, gentlemanly man.

That’s a useful clue, but it’s also a memory from more than four decades earlier, and every theory since has had to decide how much weight to give it.

Who are the main suspects?

Researchers have proposed more than a dozen candidates. These three get the most attention. Treat every row as a theory, not a fact.

Candidate	Who he was	Who proposed him	The case for	The case against
Milton Franklin Andrews	A card cheat who died in a murder-suicide in San Francisco in 1905	Martin Gardner; argued at length in The Man Who Was Erdnase (1991) by Bart Whaley, Martin Gardner and Jeff Busby	The surname fits “E. S. Andrews,” and his death would explain why the copyright was never renewed	Critics say his known writing doesn’t match the book’s style and his description doesn’t fit Smith’s memory; many researchers now doubt it
Wilbur Edgerton Sanders	A well-educated mining engineer from a prominent Montana family	David Alexander; Genii magazine gave much of its September 2011 issue to the theory	“S. W. Erdnase” is an exact anagram of “W. E. Sanders,” and he was a capable writer	No document directly ties him to the book
Edward Gallaway	A Chicago printer	Chris Wasshuber, who followed the printer’s 1903 bankruptcy records	A link to the shop that printed the book, and a forensic linguistic comparison that found a strong match in writing style	Style comparisons can suggest but not prove authorship, and the case is still debated

Other names include several more men called Andrews and, from the Spanish magician Juan Tamariz, a performer known as L’Homme Masqué. None has more than circumstantial support.

So has anyone solved it?

No. The Andrews theory dominated for decades, largely thanks to Gardner, but evidence gathered since has weakened it. The Sanders and Gallaway cases each have serious supporters and serious sceptics. Until someone finds a document that names the author outright, the honest answer is that we don’t know.

That uncertainty is part of the fun. Erdnase research has become a small hobby of its own, with magazine issues, books and long forum threads devoted to it.

Should a beginner read Erdnase?

Read it for the history and the voice, yes. Learn from it first, probably not. The writing is dense, the illustrations are small, and much of the first half is aimed at card cheats rather than performers. Some of the language and attitudes are very much of 1902, so expect to read it as a period piece.

Plenty of the techniques it describes are now taught in clearer, step-by-step form in modern books. If you want a gentler route into sleight of hand, the Royal Road to Card Magic builds its skills chapter by chapter, and our guide to card magic basics covers the foundations. If you’re wondering how long any of this takes, see is card magic hard to learn?

Once your hands are comfortable with a deck, come back to Erdnase. A lot of it makes more sense when you’ve already struggled with the moves yourself. You’ll find more to practise with in our card magic collection.

Where can I read The Expert at the Card Table?

The book is in the public domain, and we offer it as a free ebook: a complete 230-page PDF. Our scan comes from a 1905 printing by Frederick J. Drake & Co., the Chicago publisher that issued cheaper editions soon after the first. It carries a stamp marking it as part of Harry Houdini’s 1927 bequest, so you’re reading a copy from Houdini’s own library.
