René de Marmande
French journalist and art dealer (1875-1949)

Vicomte Gilbert de Rorthays (1 January 1875 – 22 October 1949), alias René de Marmande, was a French journalist and anarchist.
Life
Origins
Marie Constant Emmanuel de Rorthay de Saint Hilaire—who later took the pseudonym of René de Marmande—was born in Vannes, Morbihan on 1 January 1875.
His family were minor nobility of the Vendée, and his father was prefect of Morbihan.
Pre-war career
Marmande became a journalist, and played an active role in the libertarian and revolutionary syndicalist movements before World War I (1914–18).
He contributed to the Temps Nouveaux of Jean Grave, the Guerre sociale of Gustave Hervé and the bulletin of the Association internationale antimilitariste (AIA: International Anti-Militarism Association).
In 1906 he was appointed treasurer of Liberté d'opinion (Freedom of opinion), a committee to assist political prisoners.
Other activists in the committee included Charles Desplanques, Alphonse Merrheim, Émile Janvion, Paul Delesalle and Auguste Garnery.
In August 1907 Marmande, Amédée Dunois, Benoît Broutchoux, Henri Beylie, and Pierre Monatte were among the French delegates to the International Anarchist Congress of Amsterdam, where Marmande was rapporteur for the discussion on "anti-militarism as a tactic of anarchism".
Only eight French anarchists attended the Congress at all.
Marmande signed a proposition that said syndicalism and the material interests of the proletariat were the main basis of revolutionary activity, and another that said revolutionary trade unionism and the general strike are only means and can in no way replace the Social Revolution.

Why this record matters
“René de Marmande” is worth following because a concise public description often conceals a longer documentary argument. Here, René, Marmande and French provides the most credible route into that argument.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated May 6, 2026. The linked authority identifier is Q3427065. VIAF identifies the subject as 9980368. The Library of Congress control number is nb2001018041. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1875, 1949, 1914 and 1906.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
