On the surface, the wheelchair appears a simple machine: its function seemingly apparent and its workings relatively uncomplicated. Yet, despite this apparent simplicity, the wheelchair is a complex artefact imbued with a myriad of social as well as technical relations that act simultaneously to exclude and include, confine and liberate, shape and be shaped. The wheelchair's inextricable links to injury and illness have certainly shaped its definition as a medical device. Such a definition has labelled the occupier as passive or ill and shaped a wider understanding of the machine as a prison. Wheelchair users, however, perceive the machine as a means to independence: it enables rather than disables. We present evidence here to suggest that this is not a recent phenomenon as we show how wheelchair access has been on the political agenda for disabled people for most of the twentieth century. The paper also examines the role of the wheelchair in the development of this movement, and we suggest that, as the design of the wheelchair improved, so the demand for better access increased. The final section of the paper looks at how poorly the state and its agents understood the issue of access.
