Harry Houdini, 1920, read as an etext published at manybooks.net
Houdini reveals to us his encyclopedic knowledge of the history of certain magic tricks, who performed them, where they did it, and what variations they used. He also tells us how they actually did it. You’d think it would make more compelling reading than it does, but it’s actually fairly dry.
Still, it was interesting to learn the secrets behind some of the tricks I’ve seen, such as firewalking.
