Forensic scientist, Philippe Charlier, of the University of Versailles, and Philippe Froesch, of the Parc Audiovisual de Catalunya in Barcelona, have published their reconstruction of the face of Maximilien de Robespierre based on his death mask, contemporary portraits and the accounts of witnesses.
They have also diagnosed him as a sufferer of Sarcoidosis, which, although it sounds like an overdose of Nicolas Sarkozy, is in fact an auto-immune disease.
