Ambroise Croizat

His father, Antoine Croizat, was a blue-collar worker,[1][2] and his mother, Louise Jeannette Piccino, was a weaver. Ambroise started working in a plant at the age of 13, when his father was drafted in 1914. As a metalworker trainee, he also followed evening classes, and became a toolmaker near Lyon.

In 1917, Croizat joined the Young Socialist Movement, and then the Parti socialiste (French socialist party) in 1918. He began supporting the Section française de l'Internationale ouvrière (SFIO) in the Communist International. He participated in the great social movements of the metalworkers of the Lyon area. In 1920, he joined the Parti communiste, and became one of the leaders of Jeunesses communistes, a political youth organisation, from 1920 to 1928. In 1928,[3] he was named secretary of the Fédération unitaire des métaux (French united federation of metalworkers). From 1929 – to his death in 1951 – he was a member of the central committee and of the bureau of the federated young communist movement.[4] In 1936, he became general secretary of the Metalworkers' Federation, which then represented 20% of the total CGT members.[5]

During the 1936 French legislative election, he was elected in the second division of the 14th district of Seine.[6] He negotiated the Parisian metalworking convention, and, as a rapporteur, he presented the collective agreement to the Chamber.

He was subsequently accused of "having participated in the creation and organisation of the Groupe ouvrier et paysan",[7] and on the night of 7 October 1939, he was arrested. On 20 February 1940, he was ejected from the Legislature, and on 3 April 1940, he was sentenced to five years in prison, the loss of his civil and politic rights, and a fine of 4000 francs.[8][9] After having been moved between 14 prisons, he was eventually detained during March 1941 in the bagne of Maison Carrée, near Alger. Freed on 5 February 1943, three months after Operation Torch, he was summoned by the CGT to be a member of the consultative commission of the interim government of Alger. After the Libération of France, he again served as an elected official, first in the two constitutive assemblies (voted on 21 October 1945 and 2 June 1946) and then in the National Assembly from 1946 to 1951.

Croizat served as Minister of Labour under the général de Gaulle from 21 November 1945 to 26 January 1946, and Minister of Labour and Social security from 26 January to 16 December 1946 (governments of Felix Gouin and Georges Bidault) and from 22 January to 4 May 1947 (government of Paul Ramadier, to the end of the communist participation in the government).

He participated in the foundation of the Social security system: health insurance, pension system, child benefit, and broad reform of French labour laws, through the creation of employee representative committees, occupational medicine, regulation of overtime, and a change of statute for miners.[4]

Croizat's first wife was Germaine Marie Girod (1902–1977). They divorced and, in 1939, he married Denise Mettetal (1912–1972), with whom he had two children (a daughter in March 1939, and a son in February 1940).[2]

In 1951, Croizat died of lung cancer. The Communist Party organized his funeral, with visitation at the Metalworkers House (now called Maison des métallos) at the CGT siege; historian Michel Étiévent later estimated that a million people attended.[4] He was buried in Père Lachaise Cemetery.[10]
