Aldo Cláudio Felipe Bonadei, widely known as Aldo Bonadei (São Paulo June 17th, 1906 — São Paulo, January 16th, 1974) was a Brazilian painter. As a member of the Grupo Santa Helena he was distinguished for his erudition. His varied interests made him develop work in poetry, fashion and theater. Bonadei was culturally important in the 1930s and 1940s, when modern art was being consolidated in Brazil. He was a pioneer of the abstract art in that country. In the end of the 1950s, he worked as costume designer for Nydia Lícia & Sérgio Cardoso company, and in two films by Walter Hugo Khoury.
