Anna Castelli-Ferrieri (1920 - 2006) born in 1920 in Milan, where she studied architecture, graduating in 1943. She was one of the first women to graduate from the prestigious Milan Polytechnic Institute. In 1949, she and her husband, Giulio Castelli, founded Kartell, which became a leading furniture company known for high-quality plastic designs.

She was a pioneering architect associated with the postwar period of Italian modern design, known for its embrace of technological innovation and audacious style.

She developed many new products with them using plastics as well as polyurethane, polystyrene and polypropylene, some of which items are still in production today.  Featured on Epure Design is her 1969 "Componobili," stackable round plastic containers; of which the Bloomingdale's created an entire New York skyline out of them in its home furnishings department.
