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 São Paulo.
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.
