Marco Zanuso, one of Italy's leading postwar designers and an architect known for a functional yet elegant style, died Wednesday in Milan after a long illness. He was 85.
Zanuso was among the furniture designers responsible for convincing people that plastic was a suitable material for the home. With his partner, German designer Richard Sapper, he designed a small, stackable child's chair in 1961 and manufactured it in several playful colors. The light, functional piece was instantly popular.
