The difference engine is a case study in what media archaeologists see as a diversity of temporalities entangling the production and functionality of technological media. Only an unfinished prototype, what was called “Babbage’s beautiful fragment” existed of Babbage’s designs during his lifetime. Even so, many machinists created their own variations of the difference engine after Babbage’s death. This phenomenon, and the many troubles Babbage himself ran into regarding the materials used to create the difference engine, demonstrates that the machine’s functionality exceeded its inventor’s intentions and awareness.

The manufacture of artificial limbs was a Victorian growth industry, requiring an assortment of qualifications: mechanical skills, sympathy for the disabled, commercial ambition, a willingness to exaggerate in advertising, and faith in technological progress. This essay explores nineteenth-century designs for artificial hands, focusing on the stories they relay about the relationships between the people who needed artificial hands and the people who made them. These relationships concertize and personalize the complex factors at play in the history of Victorian hand prostheses: philosophies of embodiment, the hand’s role in these philosophies, the experiences of people without a hand or hands, and the impact of technology on all three.
