He was the son of Marie Emilie Hélène Vavin (known as Hélène) and Dominique Parodi, who was a philosopher and a member of the Institut de France. His grandfather Dominique-Alexandre Parodi was a poet and dramatist. The family was a republican one. Parodi became an auditor for the Conseil d'État (France) in 1926. From 1929 to 1938 he was deputy secretary-general of the Conseil national économique (National Economic Council), now the Conseil économique, social et environnemental. He married Anne-Marie Vautier on 2 January 1931 in Switzerland. In 1938 he became Maître des Requêtes, a high-ranking legal administrative officer, for the Conseil d'État (civil service), a technical advisor for the ministry of labour and the following year the director-general of labour and manpower.[1][2][3]
Although he was a lieutenant in the infantry reserve upon the outbreak of World War II, he was not called up because of his civil-service role.
In October 1940, he was dismissed by the Vichy régime which suspected him of anti-Vichy feelings ("mal penser") and returned to the Conseil d'État now in the Puy de Dôme. From 1942, he made frequent trips to Haute Savoie and also visited his wife who was unwell in Switzerland nearby. At this time, his brother, the magistrateRené Parodi, part of the Liberation-Nord resistance movement, was arrested by the Gestapo; he was found hanged in his cell in April 1942. In Haute Savoie, Parodi met two politically-active professors of law, François de Menthon and Paul Bastid (the latter also dismissed by Vichy), and lawyer Robert Lacoste; the four founded, at Jean Moulin's suggestion, the Comité des Experts, which became the Comité général d'études at the end of 1943. Using the name Quartus, Parodi and his collaborators discussed post-occupation administrative arrangements.[1][2][4][5]
In summer 1943, following the seizure of general-delegation documents by the Gestapo in Paris, he went into hiding. In September 1943, he was appointed head of the commission clandestine de la Presse et de l'Information. He also took part in the creation of the comité financier de la Résistance. In March 1944, Charles de Gaulle replaced Jacques Bingen with Parodi as the general delegate of the Comité Français de Libération Nationale (CFLN), the provisional administration coordinating resistance and making preparations for government after liberation from the Nazis.[1][6][2][4]
In August 1944, using the alias "Cérat", he was made Minister of the Liberated Territories and took up the role in Paris when the insurrection began. On 17 August, he obtained from the Conseil national de la Résistance (CNR) permission to suspend the outbreak of the insurrection. On the 19th, to keep the resistance united, he agreed with the CNR and the Comité parisien de la Libération to the proclamation of the insurrection, without informing the leader of the Free France forces, General Koenig. He placed the Parisian resistance under the control of Colonel Henri Rol-Tanguy. With two assistants, engineers Roland Pré and Émile Laffon, he was arrested on 20 August by the Nazis when a truce proposed by the Swedish Consul-General Raoul Nordling came into force. He openly admitted his ministerial status and insisted on meeting General Dietrich von Choltitz, military commander of Paris, who released them presently. On 21 August, the truce was broken and on 22 August, Parodi chaired a meeting of the provisional secretaries of state at the Hotel de Matignon to set up the new administration. On 25 August, the day von Choltitz surrendered, he welcomed de Gaulle to Paris. On 27 August, de Gaulle appointed him Compagnon de la Libération.[1][2][4]
From September 1944 to November 1945, he was the Minister of Labour and Social Security and oversaw the introduction of the French national health service. He was appointed a state councillor in December 1945, and began a diplomatic career in 1946; the same year he was the main French delegate in making Allied arrangements with Italy. He was the permanent delegate of France to the United Nations Security Council. In 1949, he was secretary-general of the Ministry of Foreign Affairs. In 1955 he became the permanent representative of France to NATO. From 1957 to 1960, he was the first French Ambassador to Morocco before being appointed vice-president of the Conseil d'État, succeeding René Cassin. From 1964 until 1971 he was part of the World Court in the Hague. He was President of the Fondation nationale des sciences politiques, a member from 1970 of the Académie des sciences morales et politiques and of the council of the Ordre de la Libération. He retired in 1971 and was honorary president of the Conseil d'État.[1][2][4]
He died on 15 March 1979 at home in Paris and was buried in Père Lachaise cemetery.[1][2]
