On 16 September 1856, gentleman illusionist Jean-Eugène Robert-Houdin embarked from Marseille on the steamship Alexandre bound for the embattled French colony of Algeria. Thirty-six hours later, a detachment of French soldiers met him in the port of Algiers. Recently retired as an entertainer to pursue research in optics and the emerging field of applied electricity, Robert-Houdin was about to return to the stage in a series of magic performances that a French general purportedly called the most important campaign in the pacification of indigenous Algeria (Chavigny 1970: 134).
