He was born in Holland a long time ago. Amongst his teachers he was lucky enough to have Gerrit Thomas Rietveld from the Dutch De Stijl group; later he studied in Ulm at the Hochschule fuer Gestaltung with Tomas Maldonado, Walter Zeischegg and Max Bill. He started as a designer at Olivetti in Italy as an assistant of Ettore Sottsass; later he opened my own studio in Milan where his wife Hiroko Takeda joined him. They created many products in different sectors, such as household applyances, furniture, machine tools and electronic equipment. From the very start he was also interested in the theoretical aspects of design, such as design language, morphology and semiotics, and he spent much time as a teacher, to write articles and even two books (in Italian).
