This unique book documents the work and lives of two 20th-century architects, Lina Bo Bardi and Albert Frey, whose shared beliefs anticipated todays architectural principles of integration among humans, earth, and the built environment. This book proposes a dialogue between two key 20th-century architects, Albert Frey and Lina Bo Bardi. Frey moved from Switzerland to the U.S. in the early 1930s and Bo Bardi emigrated from Italy to Brazil after the end of World War II. While they never met, their intellectual odysseys overlapped. Both fostered the integration among architecture, landscape, and people, helping transform the architectural culture in their adoptive countries. Their design affinities converged in the notion of a living architecture, evident in their publications and the projects featured here
