"Autobiography," said Longfellow--altho the remark does not seem especially characteristic of this gentle poet--"is what biography ought to be." And in the long list of alluring autobiographies, from Cellini's and Cibber's, from Franklin's and Goldoni's, there are few more fascinating than the 'Confidences of a Prestidigitator' of Robert-Houdin. A hostile critic of Robert-Houdin's career has recorded the fact--if it is a fact--that Robert-Houdin once confided to a fellow magician that his autobiography had been written for him by a clever Parisian journalist; and it must be admitted that not a few amusing French autobiographies have not been the children of their putative parents--for instance, the memoirs of Vidocq, the detective. Yet this is not as damaging an admission as it may seem at first sight since the clever Parisian journalist may have been little more than the amanuensis of the prestidigitator, hired only to give literary form to the actual recollections of his employer. Such a proceeding would not deprive Robert-Houdin's autobiography by its authenticity. It remains a classic, beloved by all who joy in the delights of conjuring. Unfortunately the hostile critic has gone further in his attack upon Robert-Houdin's reputation, and he has succeeded in showing that the renowned French conjurer claimed as his own invention not a few illusions which had been already exhibited by his predecessors in the art of deception. Yet this unjustified boasting does not invalidate Robert-Houdin's title to be considered the father of modern magic. Even if he was treading in the path of those who had gone before, he attained at last to a consistent theory of the art, far in advance of that held by earlier magicians. Many of his marvels, and perhaps more than one of the most striking of them, may have been but improvements upon effects originally contrived by others; yet every succeeding generation can rise only by standing upon the shoulders of the generations that went before, and it is justified in availing itself of all that these earlier generations may have discovered and invented. Robert-Houdin tells us himself that he was greatly indebted to the Comte de Grisy, whose stage-name was Torrini. In fact, Robert-Houdin might be called a pupil of Torrini, as Mr. John S. Sargent is a pupil of Carolus Duran. It was upon Torrini's dignified simplicity as a magician that Robert-Houdin modelled his own unpretending presentation of his feats of magic. Apparently it was a famous conjurer named Frikell, who first discarded the cumbersome and glittering array of apparatus which used to be displayed on the stage to dazzle the eyes of the spectators; but this discarding of obtrusive paraphernalia was not deliberate, being due only to the accidental destruction of Frikell's stage-furniture by fire, whereby the performer was suddenly forced to rely upon the less complicated experiments, which could be exhibited without extraneous aid. The abandoning of overt
