This magnificent wheelchair, upholstered in lemon-coloured velvet, once belonged to Robepierre's ally on the Committee of Public Safety Georges Couthon. The wheels are moved by means of two cranks attached to the arms. It is reproduced to dramatic effect in the film Danton - see below. (If the chair doesn't appear immediately it is about 1 minute 40 into the clip.)
The chair first appeared in July 1899 when it was presented out of the blue to the Musée Carnavalet by a woman who refused to give her name but identified herself as Couthon's great-granddaughter. She claimed that it had been in store with the family furniture ever since Couthon's execution on 9th Thermidor.
