Born in Milan in 1907, he soon joined the Futuristic movement, taking part in various exhibitions.
From 1939 to 1945 he worked as a graphic with the publisher Mondadori and as art director of Tempo magazine, while started to write children's books. In 1948 he founded the MAC (Concrete Art Movement), a movement promoting non-figurative art, and in particular a kind of abstraction free from imitation and reference with the outside world, which mainly had geometric orientation.
He was one of the leading protagonists of art, design and artwork of the XX century, making fundamental contributions in several fields of visual art (painting, sculpture, cinematography, industrial design, graphic design) and non-visual art (writing, poetry, teaching) with a multifaceted research on movement, light and development of creativity and imagination of childhood through play. After several important awards in honor of his vast activities, Munari made his last work a few months before his death in 1998 at age 91, in Milan.
