Architect César Pelli (San Miguel de Tucumán, Argentina, 1926-New Haven, Connecticut, 2019) is one of the architects of greatest international projection. He graduated from a school of avant-garde design: the Instituto de Arquitectura y Urbanismo of the Universidad Nacional de Tucumán, that incorporated the idea of the pioneers of the Modern Movement. His architectural firm Pelli Clarke Pelli Architects is an important part of his work: it is there that urban fabrics and architectural plots are projected for the construction of a more human and more beautiful world. The book begins with an essay that includes his works in Buenos Aires, continues his biographical journey and is completed with the collection of his recent projects in the United States, Spain and Argentina.
