Nicolas Fouquet is the Man in the Iron Mask

Nicolas Fouquet is the Man in the Iron Mask according to a thesis put forward by Paul Lacroix and then taken up by Pierre-Jacques Arrèse. Imprisoned at Pignerol from 1665, the superintendent allegedly saw his sudden death announced in March 1680 to prevent his imminent release desired by Louvois and Colbert. The ministers allegedly disguised his death by using the name of the valet Eustache Danger, before sending him six years later to the Île Sainte-Marguerite.
