Perhaps the single most elusive name in the cannon of card-table deceptions is S.W. Erdnase. Author of what has, for many, become the Holy Bible of card technique (The Expert at The Card Table), S.W. Erdnase permanently revolutionized how our forefathers approached a deck of cards.
Whether he really was S.W. Erdnase, E.S. Andrews, or anyone in between we'll never know. What we do know, however, is that a man in 1902 whom we call Erdnase shaped the art as we know it today. For that we thank him.
