Yona Friedman In 1958 Yona Friedman published his first manifesto on "mobile architecture" and founded GEAM (Groupe d'Etude d'Architecture Mobile), which proposed different strategies and actions geared to the adaptation of architectural creation to modern user requirements for social and physical mobility. In this initial manifesto, Friedman claims that architectural knowledge cannot be the exclusive property of professionals and specialists, and suggests writing guides or manuals, which explain topics related to architecture and urban planning in clear and simple terms. Pro Domo is "a collection of fragments of scattered topics," a set of "milestones" selected by the author himself, a personal selection chosen "according to sentimental value", spanning 50 years of production.
