Robespierre
Maximilien de Robespierre was one of the most prominent, but also infamous figures of the French Revolution. He was behind an appalling number of executions of nobility and royalty members, as well as of other people suspected to be agents contrary to the Revolution.
In the end, he himself was executed by his political enemies. Researchers Philippe Froesch and Philippe Charlier created this rendering of his face, relying on artwork and two death masks.
