Aldo Cláudio Felipe Bonadei, also known as Aldo Bonadei (São Paulo June 17, 1906 — São Paulo, January 16, 1974) was a Brazilian painter of Italian descent.
Early life 
Between 1923 and 1928, Aldo studied with Brazilian academic painter Pedro Alexandrino and frequently visited the studio of Italian painters Antonio Rocco and Amadeo Scavone who also lived in Sao Paulo. During this period, he studied at the Liceu de Artes e Oficios de Sao Paulo, where he took courses on sketching and Fine Arts.
Italian Influence 
In the beginning of the 1930s, Aldo decided to move to Florence to attend the Florence Academy of Arts (Accademia di Belle Arti di Firenze) where he trained as a painter with the Italian artists Felice Carena and Ennio Pozzi. When he returned from Italy, Aldo shared his studio with other fellow artists such as Francisco Rebollo, Alfredo Volpi, Mario Zanini, Manuel Martins and Fulvio Penacchi, forming group that later became known as Grupo Santa Helena.
A Pioneers School 
In 1949, Aldo began to teach at what became the first school of Modern Art in Sao Paulo, Escola Livre de Artes Plásticas. His varied interests led him to work in poetry, fashion and theater. He was culturally important in the 1930s and 1940s, when modern art burgeoned in Brazil, becoming a pioneer of Brazilian abstract art.
At the end of the 1950s, Aldo worked as costume designer for Nydia Lícia & Sérgio Cardoso company, and in two films by Walter Hugo Khoury.
