Achille Castiglioni was an Italian architect and designer of furniture, lighting, radiograms and other objects. As a professor of design, he advised his students "If you are not curious, forget it. If you are not interested in others, what they do and how they act, then being a designer is not the right job for you."

Giannino Castiglioni was an Italian sculptor and medallist. He worked mostly in monumental and funerary sculpture; his style was representational, and far from the modernist and avant-garde trends of the early twentieth century.
