Vincentelli Perini trained at the Dental School in Paris. There she discovered the Union fédérale des étudiants. She met her future husband Laurent Casanova in this organisation. In 1928 she joined the Communist Youth. She began to call herself "Danielle" and quickly became Group Secretary to the Faculty of Medicine. Still studying, she joined the Central Committee of the movement at the Seventh Congress of June 1932, and took up its direction in February 1934 where she was the only woman. Faced with the rapid expansion of the Communist Youth, the Eighth Congress in Marseilles of 1936 charged her with creating the UJFF. This organisation, though still close to the Communist Youth, was aimed at creating a pacifist, anti-fascist movement. She was elected Secretary General of the UJFF at its First Congress in December 1936, and organised a collection of milk for Spanish children who were victims of the Civil War. After the French Communist Youth was banned in September 1939, Danielle Casanova went into hiding. She wrote for the newspaper Le Trait de l'Union. From October 1940, after the fall of France, she helped set up women's committees in the Paris region, while still writing for the underground press, especially Pensée Libre. She also founded la Voix des Femmes. She organised demonstrations against the occupying forces, including the events of 8 November and 11 November 1940 caused by Professor Paul Langevin's arrest, and also that of 14 July 1941. On 2 August 1941 Casanova met Albert Ouzoulias in Montparnasse and placed him in charge of the Bataillons de la Jeunesse, fighting groups that were being created by the Jeunesses Communistes. French Police arrested Casanova on 15 February 1942 while she was aiding Georges Politzer and his wife. Transported to Auschwitz on 24 January 1943, she served in the camp infirmary as a dentist. She helped other women from the convoi des 31,000 that brought them to Auschwitz, introducing Maïe Politzer as a doctor and others including Madeleine Passot as nurses. She did not stop campaigning, organizing clandestine publications and events, even in a concentration camp. She died of typhus on 9 May 1943.
Legacy
A heroine of the Resistance, she has lent her name to streets, schools, and colleges throughout France. A ferry between Marseilles and Corsica also bears her name. Simone Téry wrote a biography of her.
