Leopoldo Piccardi (Ventimiglia, 12 June 1889 – Rome, 18 April 1974) was an Italian politician and civil servant, who served as Ministry of Industry and Commerce of the Badoglio I Cabinet, the first after the fall of the regime. After the war he became a founding member and secretary of the Radical Party until a scandal over his participation in anti-Semitist conferences during the Fascist period forced him to resign.
During a meeting of the Central Committee (Rome, 18 December 1955), Piccardi and his group explained the reasons why they would detach from the movement.[12] During 1955 Piccardi had participated in some meetings organized by the "Friends Il Mondo", and formed an executive committee in charge of creating a new liberal democratic party, which was established on 5 February 1956 with the name of Radical Party.[13] Parri and Arrigo Olivetti (a liberal among the founders of Il Mondo, brother-in-law of the better known Adriano Olivetti) later passed from Popular Unity to the Radical Party as well.[14] On 28 February 1959 Piccardi was elected to the post of secretary of the Radical Party, together with Franco Libonati, Arrigo Olivetti and Eugenio Scalfari. On 6 November 1960 he was to the city council of Rome.[15]
In 1961 historian Renzo De Felice, in a new book on the history of Italian Jews under Fascism, revealed that Piccardi, as a member of the Council of State, had participated in 1938 and 1939 in two Italian-German legal conferences on the theme "Race and law", which had contributed to the theoretical elaboration of the Italian racial laws.[16][17][18] In December 1961 Mario Pannunzio and other members of the "Friends of Il Mondo" condemned Piccardi, asking for his resignation from the Radical Party, while Ernesto Rossi and Ferruccio Parri supported him.[19][20][21] The party secretariat and leadership resigned; internal strife went on for a few months, and the Radical Party essentially disintegrated, with most of its member going over to the Italian Socialist Party.[22][23][24] In October 1962 Piccardi, together with other radical exponents, asked for the dissolution of the party and its merger into the Italian Socialist Party, but internal conflicts pushed him to resign.[25][26][27]
