Gianni Pettena (Bolzano, 1940) is an architect, artist, critic and architectural historian. He was a member of Global Tools, professor of the History of Contemporary Architecture at the University of Florence, and also taught at the State University of Florence and the Architectural Association in London. Co-founder and inspiration in the late 1960s of the Italian Radical Architecture movement, from which much contemporary experimentation in the field of architecture and design stems, he carries out experimental work aimed at eliminating disciplinary boundaries and revisiting and reinventing alphabets and languages ​​through projects, furniture, installations, exhibitions, theoretical writings, essays and texts. The uniqueness of his long career lies in his rejection of discipline-based roles and methodologies, creating temporary works and constantly seeking alliances with conceptual art, Austrian radical design, Land Art and experimental music. His work has been presented in museums and institutions such as the Venice Biennale, the Mori Museum in Tokyo, the Barbican Centre in London, the PAC in Milan, the Museion in Bolzano, the Centre Frac in Orleans and the Pompidou Centres in Paris and Metz. His archive is held at the CCA in Montreal.
