Jean-Eugène Robert-Houdin, “The Father of Modern Magic,” 1868:
It is easy enough, no doubt, to play the conjuror without possessing either dexterity or mental ability. It is only necessary to lay in a stock of apparatus of that kind which of itself works the trick. This is what may be called the “false bottom” school of conjuring. Cleverness at this sort of work is of the same order as that of the musician who produces a tune by turning the handle of a barrel-organ. Such performers will never merit the title of skilled artists, and can never hope to obtain any real success.
So beware of the “false bottom” or “push button” school of (pseudo) conjuring!
