• Minister of Labor and National Solidarity Marcel Déat, 1894
• Ambassador of Vichy France to the United States Gaston Henry - Haye, 1890

Marcel Déat was raised in a modest environment, which shared republican and patriotic values. After brilliant studies, he entered in 1914 the École Normale Supérieure (ENS) after having been the student of Alain, a philosopher who was active in the Radical Party and who would write a deeply anti - militarist book after World War I. The same year, Déat joined the SFIO.

While he attended the ENS and worked to get a philosophy degree, World War I broke out. He joined the French Army as a private and saw active duty, winning the Légion d'honneur and five bravery citations. By the war's end, Déat had achieved the rank of captain. Under the pseudonym of Taëd, he then published Cadavres et maximes, philosophie d'un revenant (approximately translated by "Corpses and Maxims, Philosophy of a Ghost"), in which he expressed his horror of trenches, strong pacifist views, as well as his fascination for collective discipline and war camaraderie. When the war ended in 1918, he finished his studies at the École Normale and passed his agrégation of philosophy, and oriented himself towards sociology under the direction of Célestin Bouglié, a friend of Alain and also member of the Radical Party. In the meanwhile, Déat taught philosophy in Reims.

During the 1920 Tours Congress in which a majority of the SFIO decided to spin off to found the French Communist Party, Marcel Déat positioned himself at the right wing of the SFIO, taking part to the groupe de la Vie socialiste current, alongside Pierre Renaudel.

Déat was elected municipal counselor of Reims in 1925, and then deputy for the Marne during a partial election in 1926. However, he lost his seat after the 1928 elections. In these times, Léon Blum, the leader of the SFIO, tried to favor youths in the party, and decided to name Déat secretary of the SFIO parliamentary group. After having been put in charge of the documentary center of the ENS by Célestin Bouglié, Déat now founded a documentary center for the SFIO deputies.

Marcel Déat published in 1930 Perspectives socialistes (Socialist Perspectives), a revisionist work closely influenced by Henri de Man's planisme. Along with over a hundred articles written in La Vie Socialiste, the review of the SFIO's right wing, Perspective socialistes marked the shift of Déat from classical Socialism to Neo - Socialism. Déat replaced class struggle by collaboration of classes and national solidarity, advocated corporatism as a social organization model, replaced the notion of "Socialism" by "anti - Capitalism" and supported an authoritarian state which would plan the economy and from which parliamentarism would be repealed.

During the 1932 elections, he was elected deputy of the 20th arrondissement of Paris, beating the Communist Jacques Duclos — who himself had gained the upper hand against Léon Blum in 1928 in the same electoral district. Déat and other Neosocialists were expelled from the SFIO at the 5 November 1933 Congress, for their revisionist views and disagreements with Léon Blum's policies toward Prime Minister Édouard Herriot, leader of the second Cartel des Gauches (Left Wing Coalition). The official position of the SFIO was then to support the Cartel without participating to the government, considered as "bourgeois." The same year, Déat joined the Socialist Party of France - Jean Jaurès Union (PSdF) created the same year by Planist and Neosocialist elements expelled by the SFIO during the 1933 Congress. The new party's slogan was "Order, Authority and Nation".

The expelled faction was a minority in the SFIO, but represented the majority of the SFIO parliamentary group. They were opposed both by the left wing of the SFIO, represented by Marceau Pivert, and by the SFIO's center, headed by Blum. The Neosocialists wanted to "reinforce the state against the economic crisis", open themselves to the middle classes and participate to non - Socialist governments.

Without the support of the Socialists, Déat lost his seat in the Chamber. Two years later, he joined the Socialist Republican Union (USR). He became Minister of Air in the "bourgeois" government of Albert Sarraut (Radical) but he quickly resigned his post over disputes with the Prime Minister. With the increasing threats represented by Nazi Germany, Déat wanted to maintain peace at any cost.

He returned to the Chamber of Deputies in 1936 as a delegate from Angoulême, and at first supported the Popular Front led by Blum before denouncing "Communist infiltration" of it. After Blum's replacement by Édouard Daladier in 1938, which marked the end of the Popular Front, Déat participated to the "Anti - Communist Rally." The same year, he explicated his support of the Munich Agreement in an article titled Mourir pour Danzig? (Why Die for Danzig?) and published in the newspaper L'Œuvre. There, he argued that France should avoid war with Germany if the latter seized Poland - the publication caused a widespread controversy, and propelled Déat to national fame. Déat would collaborate with L'Œuvre during the entire period of Vichy France.

A strong supporter of Germany's occupation of northern France in 1940, Déat took up residence in Vichy France, and was initially a supporter of Philippe Pétain. He attempted to create a single party in order to fully realize the aims of the "Révolution nationale", the official, reactionary ideology of Vichy. Thereafter, he founded in February 1941 the National Popular Rally (RNP) which advocated Collaboration with Nazi Germany and anti - Semitism.

When Vichy, then headed by Pétain, did not become the Fascist state Déat had in mind, he moved to occupied Paris and was funded by the Germans. The Nazis forced Déat at first to merge his new party (RNP) with Eugène Deloncle's MSR (Social Revolutionary Movement), a far right party inheritor of the Cagoule terrorist group. The merger was a failure and Déat later expelled MSR elements from his party, before trying to form a unified front of Collaborationist parties.

Déat also founded, along with fellow Collaborationists Jacques Doriot and Marcel Bucard, the Légion des Volontaires Français (LVF), a French unit of the Wehrmacht (later affiliated with the Waffen - SS).

While reviewing troops from the LVF with Vichy figure Pierre Laval in Versailles on 27 August 1941, Déat was wounded in an assassination attempt - carried out by French Resistance member Paul Collette. After recovering, he became a supporter of Pierre Laval, who supported more reactionary policies than Pétain and had become Prime Minister of the Vichy regime in 1942. Under the suggestion of the Germans, Marcel Déat became on 16 March 1944, "Minister of Labor and National Solidarity" in Laval's cabinet.

After the Allied landings at Normandy and the fall of the Vichy government, Déat fled to Germany and became an official of the Vichy government in exile at Sigmaringen. With the fall of Germany in 1945, Déat fled to Italy in April and assumed a new name, temporarily teaching in Milan and Turin. He was later taken in and hidden by a religious order in the convent of San Vito, near Turin, where he wrote his memoirs and lived undiscovered until his death in 1955. After the war, he had been convicted of treason and sentenced to death in absentia by a French court.

He served in the French Chamber of Deputies from 1928 to 1935, and in the French Senate from 1935 - 1944. He was also Mayor of Versailles from 1935 - 1944. Henry - Haye voted full powers to Marshal Philippe Pétain on 10 July 1940, and was appointed by Petain as Ambassador of Vichy France to the United States in 1940 after the armistice between Vichy France and Germany. His photograph was featured on the cover of Time Magazine, 10 March 1941.

Henry - Haye was interned by the United States in 1942, following the occupation of Vichy France by Nazi Germany. This internment of a diplomat was unusual, as no state of war existed between Vichy France and the United States. He was allowed to return to Vichy France in 1944, but escaped to South Africa after threats of death by the French Resistance. Henry - Haye returned to France in 1950. He returned to public notice in 1966 when he successfully sued author H. Montgomery Hyde for libel.
