Houdini wrote a very nasty book about Robert-Houdin claiming that Robert-Houdin stole many tricks and was in reality not as great a magician as he usually is portraied. Jean Hugard sets with this book the record straight and reveals Houdini’s fabricated arguments. Houdini’s unmasking of Robert-Houdin was just a revenge on Robert-Houdin’s family and had little to do with reality. But you can find out for yourself and read The Unmasking of Robert-Houdin.
“Houdini’s Unmasking” originally appeared as a series in Jean Hugards magazine Hugard’s Monthly Magic Publication.
