'Professor' John Henry Pepper collaborated with English engineer Henry Dirck in the 1860's to create an optical device for use as a stage illusion that allowed a 'ghost' to be projected onto the stage. The effect's debut was in a show entitled 'The Knight Watching His Armour' at the London Polytechnic Institute, where Pepper was a professor.

'Sitting for their carte-de-visite' is reference to the 'Cartomania' that was sweeping England in the 1860's.
