Erdnase Resources

Last Update: 01/21/2021 (Replies:0)

by Chris Wasshuber

The search for S.W. Erdnase has and is being conducted by a small but very dedicated group of investigators, historians, magicians, and gamblers. I am part of this group of investigators. While we often champion entirely different candidates and disagree on many points there is something to be learned from each point of view. The list below is a chronologically sorted list of books and articles which I consider important reading on the subject:

A Rowing Machine which Generates Electricity

Last Update: 04/11/2020 (Replies:0)

After I had too much pain in my knees running, I decided to switch to a lower impact exercise. The obvious choice would have been cycling, but I discovered rowing and liked the fact that it trains more muscles, because it also exercises the upper body. I like to be efficient with my exercising. I don't have all day just to exercise. An exercise that engages more of my muscles is therefore more time efficient. It also produces lower joint impact than running. Cycling is even lower impact than rowing,...

Triple Gozinta Boxes

Last Update: 04/05/2020 (Replies:5)

Go figure this one out. Three boxes, big, medium, small, stacked inside each other. So far so good. But hey, what is this? The small box is now large enough to hold the medium and big boxes?

This is my rendition of Lubor Fiedler's ingenious Gozinta Boxes (also known as Parabox or Inside-Out box). (The reason I am touching the boxes so gingerly is that they are 20 years old made from now brittle cardboard. Nevertheless, this effect is one of my favorite illusions.)

Jason England's 17 Card Books to Study

Last Update: 01/11/2020 (Replies:0)

In September 2010 Theory 11 released a short video clip where Jason England introduced 17 books on card magic any serious card magician should read. It was titled "An instructional download on the things you can't download" (my emphasis). Well, I respect the talented guys at Theory 11, but they are a bit behind the curve when it comes to downloads, because 10 of the 17 books are available as download ebooks from - and most of them for many years. One book is available as ebook from...

The Many Uses of The Shuber Blades

Last Update: 01/11/2020 (Replies:0)

The Shuber Blades are a flexible accessory to protect your playing cards. Two stainless steal blades together with a special rubber band secure your cards regardless of if you want to protect one card or more than a regular deck of cards.

You can not only protect your cards, but you can also use the Shuber Blades to build a pocket card press. Take two large paper clips of the kind shown below.

Who Can Decipher the Title and Author of these Books

Last Update: 10/03/2019 (Replies:0)

Below are two snippets of photos which show the backs of three books. These books must have been published before 1923. Very likely these are well known classics. If you can figure out the title of any of these please contact me.

After posting this I figured out the lower one of the two shown above. It seems to be Civil Wars and Monarchy in France by Leopold von Ranke (1852).

Edward Gallaway is S. W. Erdnase

Last Update: 09/12/2019 (Replies:0)

To read the full story, the full case why Edward Gallaway is Erdnase, get my ebook The Hunt for Erdnase: and the path to Edward Gallaway.

I know this will come as a shock to some, particularly those who hold on to the old rumor that it was an Andrews. However, this rumor cannot be substantiated. We have to trace this back from Vernon to Sprong to a Drake son who would have to get it from his father who we don't even know had any direct contact with Erdnase. Yet some believe this like it is an irrefutable fact. Let me give you the news, it isn't. It...

Anverdi-type Haunted Card Box

Last Update: 08/17/2019 (Replies:8)

In the mid 90s I played around with incorporating electronics into magic. Anverdi had a great idea where a box would close just before a spectator selected card could be placed inside it. I didn't like the mechanics of his box, which was a box for two decks where one half was used for the electronics and the other half for the actual action. The sliding lid of the box would slowly close. Here is a video for the original Anverdi box:

After I read Anverdi's book I could build the variation...

A List of Al Mann Publications

Al Mann was a prolific writer who published in excess of 100 manuscripts primarily on mentalism. All the Al Mann products we have for sale on can be found on the Al Mann author page. Since we have already sold out of many of his manuscripts the list there is not complete. As we sell out more and more it will further shrink. To help Al Mann collectors complete their collection I am listing below all the manuscripts and books that are known to me. It is easily possible that I am missing one or the other....

How To Make Your Own Playing Cards

If you have been struggling with making your own gaffed cards, printing your own deck of cards, or if you always wanted to put uncle Joe's face where the Jack of Spades is, then now this has become a lot easier and cheaper than ever before. The method I will describe here results in cards that are identical in look and feel to regular USPCC cards. And the best of all of this is that you can do this for a few cents per card right at home. ...

Cy Endfield's Chess Set

Cy Endfield was a film director, magician and inventor. Among his many achievements he created a unique chess set which he patented in 1974 in the US (3,806,128). This chess set, which allows one to interlock all back row pieces into a tube for easy storage, was the official FIDE commemorative chess set for the legendary 1972 chess battle between the American chess genius Bobby Fischer and the Russian protege Boris Spassky.

Largest Origami?

Last Update: 12/24/2018 (Replies:0)

On October 19th 1994 I created a giant origami model using a square sheet of paper measuring 6.36 meters on each side. Total weight was 5.45 kg. I made the fold inside the largest paper factory in Austria, Leykam Muerzthaler. I used the entire width of the paper the factory manufactured. Just to cut off a perfectly square piece of such a large piece of paper was a challenge.

Non-Evaporative Cheap Portable Air Conditioning

Last Update: 12/24/2018 (Replies:0)

I decided to combine some of the ideas I found online how to make a cheap non-evaporative air-conditioner. The basic idea is to blow air through ice or cold water to cool it down. The simplest solution is to fill a cooler with ice and have a fan blow air into the cooler and out from another opening comes cooler air. But that simple solution does not provide a lot of air/ice surface for heat exchange. Particularly once the ice starts melting the pool of water reduces the exchange surface and thus...

Business Card Strategies

Last Update: 12/24/2018 (Replies:3)

Over the years I had a couple of pretty lame business cards. You know the kind that your employer issues to you or the ones you print out yourself after an hour of fiddling around with a graphics software. During the last years I did not have a business card. While I am not great at handing out my business card, I do get occasionally asked if I have one, and then I am embarrassed that I don't have one. The most recent such incidence prompted me to get a business card made. But I did not want to...

The Learned Pig Project: TLPP

The Learned Pig Project

The Learned Pig Project was started in September 1999 by Marko from Panama. Marko's idea was essentially to mimic the Project Gutenberg for magicians. Project Gutenberg's purpose is to digitize public domain books. The Learned Pig Project's goal is to digitize public domain magic books. When Marko started he had four books digitized: My Magic Life (Devant), Miracle Mongers (Houdini), The Lives of the Conjurers (Frost) and Behind the Scenes with the Mediums (Abbott). He would later add dozens more. In...

Erdnase/Gallaway Cover Comparison

Last Update: 12/24/2018 (Replies:3)

I am firmly convinced that Edward Gallaway is S. W. Erdnase. One of many reasons are the surprising similarities between the books Gallaway published later in his life and The Expert at the Card Table. Dr. John Olsson prepared a detailed forensic linguistic analysis comparing Erdnase with Gallaway concluding a strong possibility that Gallaway is Erdnase. Beyond the linguistic match there are several other aspects that are matching, too.

  • Erdnase and Gallaway self-published their books.
  • Both had their copyrights registered...

Folding Slingshot

Last Update: 12/04/2018 (Replies:0)

As a boy I made many slingshots ever since my father showed me how. Find a y-branching twig, cut it to size, attach rubber bands, and a piece of leather to hold your projectile. I must have made dozens of them. I loved the compactness of a slingshot. I also liked to make bows and arrows but those were not weapons you could put in your pocket. And they were harder to make for a boy. Finding straight arrows was one of the problems. With a slingshot any pebble, cone, or other smallish piece of something...

Story Deck Effects

Last Update: 11/17/2018 (Replies:0)

by Chris Wasshuber

A 'story deck effect' is an entertaining story of some kind which is told with the help of a deck of cards (full deck or partial deck). At certain moments in the story the performer displays a card or a set of cards to illustrate or 'play out' the story.

Probably the most famous story deck effect is Sam the Bellhop as performed by Bill Malone. Bill Malone has to be credited for adding false shuffles and cuts to the performance turning good entertainment into a stunning and amazing signature piece....

Magic Square Effects

Last Update: 11/17/2018 (Replies:0)

I have been interested in magic squares longer than I have been interested in magic. And I have been interested in magic for a long time. It was actually a close cousin of the magic square, the magic matrix as described by Martin Gardner in one of his mathemagic books, which got me into magic. But that is a story for another day.

In this article I want to explain two simple ways to construct an arbitrary 4x4 magic square.

Twisting the Aces

Last Update: 11/29/2015 (Replies:0)

"Twisting the Aces" is one of those rare blockbuster card effects which are easy to do and have a very strong visual effect. It was developed by Dai Vernon and uses the Elmsley Count as its primary move. An exceptional trick like this spawns a lot of variations. Everybody is putting his spin on it. I personally learned a variation by Thomas Hierling from Germany from his New Wave Close-up Magic book. It was one of the first tricks I performed that truly and utterly amazed my audience. Over the years I must have done...

The Hunt for Erdnase: The Nickname Theory and the Connection to August Roterberg

Last Update: 11/29/2015 (Replies:1)

by Chris Wasshuber

(This article is a work in progress. I will add and develop certain parts over the coming months.)

The mystery around the authorship of The Expert at the Card Table and who S. W. Erdnase really was, has lead to many theories and lots of speculation. In this article I am offering a completely new theory. I call it the Nickname theory. I will also try to develop the case for August Roterberg's involvement, either as the author himself, which I think is unlikely, or his participation on some level, which I think is...

Cups and Balls

Last Update: 08/22/2014 (Replies:0)

You could easily call The Cups & Balls the oldest trick in the book. It's a trick that dates back centuries and despite being "an old trick", it's just as mesmerizing today as it was hundreds of years ago. There's never been a time in magic history, as there is today, that so many products are available dedicated to this one effect.

Its versatility is what has drawn magicians to it over and over again. The Cups & Balls isn't just one trick, it's many tricks combined into a single presentation...

The Cube 3D Printer: an independent review

I bought a Cube 3D printer a few weeks ago and have printed with it almost every day. (If you want to see one of the projects I did see my article on Cy Endfield's Chess Set.)

Popular Playing Cards

Last Update: 07/15/2011 (Replies:0)

When I started to seriously get into magic, which was in the late 80s, the most popular deck of cards was the Bicycle 808 deck either in its red or blue back variety. And most magic gaffs were produced with a Bicycle back, too. Occasionally you saw a Tally Ho or Bee back, but it was a rare event. Outside the US you could find some local brands like Piatnik or Fournier, two European brands. Bicycle was also the most popular brand outside of magic which was partly its appeal for magicians - blend...
