[2] Gualino and Venturi supported Turin painters such as Felice Casorati and the Gruppo di Sei (Group of Six), which included Carlo Levi, Francesco Menzio, Jessie Boswell, Gigi Chessa, Enrico Paolucci and Nicola Galante.
[1] In 1930, Venturi organized a retrospective exhibition of Modigliani's work in Venice based on the paintings owned by Gualino.
He left Italy, initially moving to Paris, where he wrote, advised art dealers and museum curators, and produced the first catalogue raisonné of Paul Cézanne.
After the establishment of the Vichy regime, he emigrated to the United States, living in New York City until 1945 and lecturing at a range of American universities.
Venturi was influenced by the idealism of Benedetto Croce as well as the writing of Alois Riegl and Heinrich Wölfflin.
