The work of Milanís Alessandro Mendini has greatly helped to develop Italian design, but Mendini often incorporates different cultures. He became a leader in his field by pushing boundaries and challenging convention, helping to bring about the 1970ís Radical Design movement. His 1974 Lassu chair, built atop a pyramid structure, is just one example of this. Thinking beyond furniture, Mendini also creates graphics, interiors, paintings, and architectures, his first discipline. He has also authored several articles and books and juried various architectural competitions. In 1982, he co-founded the first post-graduate design school, the Domus Academy. Currently he teaches at the University of Milan and runs the Atelier Mendini practice with his brother, Franciso Mendini.
