Madame Tussaud was forced to make death masks of people she had known. To name a few, Louis XVI, Marie Antoinette, Marat and Robespierre.
Memorial to Louis XVI & Marie Antoinette ~ by E. Gaulle & P. Petitot - St Denis Basilica, burial place of nearly every French king from 10th-18th c. During the Revolution, bodies were removed, dumped in large pits & dissolved with lime (Marie & Louis had been buried at La Madeleine). In 1815 meager remains of Louis & Marie (reputedly) were returned. In 1817 the mass graves were opened & co-mingled remains placed in an ossuary in St. Denis - marble plates list the 100s of names.

Marie Tussaud was arrested and taken to the Bastille for being a royalist supporter. Her head was shaven, a custom before being taken to the guillotine, but was pardoned. She was forced to do not only one of the more curious acts in history, but one of the most morbid. She was employed to make death masks. The first were of course the most obvious: Louis XVI and Marie Antoinette.
SAINT DENIS - La Basilique - A monument to Louis XVII, frail son of Louis XVI and Marie Antoinette. He was imprisoned with his parents, separated from his family, brainwashed to believe Revolutionary propaganda, neglected, and died in a squalid prison cell.
