Henri de Rochefort, Marquis de Rochefort Lucay (1830-1913) civil servant and critic, sub-inspector of the Paris Beaux-Arts. He was condemned under military law to life-imprisonment for his support of the Commune and exiled to New Caledonia in 1873. Four months later he and some other convicts escaped in a whale boat. He lived in Geneva and London until the amnesty made his return to Paris possible, and shortly thereafter he founded a new paper,
L'Intransigiant. Ironically, the radical Rochefort later became a follower of General Boulanger and leader of the anti-Dreyfusands.
