Born in Milan on Aug. 6, 1918, Anna Castelli Ferrieri was one of the first women to graduate from the prestigious Milan Polytechnic Institute, in 1943, with an architecture degree. In 1949, she and her husband, Giulio Castelli, founded Kartell, which became a leading furniture company known for high-quality plastic designs. With the success of Kartell, Ms. Castelli Ferrieri and her husband helped fuel the explosion of Italian modern design in the 60s, 70s and 80s. In 1976, she became the art director of Kartell and continued to experiment with different kinds of plastic. She passed away in 2006 at 87 years old due to complications from lung disease at her home in Milan. She is best known for her "Componobili," stackable round plastic containers, which continue to be popular to this day.
