Town Planning Associates

Town Planning Associates, was a design firm in New York City, that included Paul Lester Wiener, Paul Schulz, Josep Lluis Sert, which did urban design and city planning in various new or existing South American cities including Bogotá, Chimbote in Peru, and Havana. Sert’s master plan for Havana, Havana Plan Piloto , was notable for its integration of natural landscape into new urban and existing building schemes. Town Planning Associates made prominent use of patios and other aspects of Mediterranean architecture adapted to South and Central America. They employed modernist principles of the Congrès Internationaux d'Architecture Moderne (CIAM) and the Athens Charter. The Charter got its name from the location of the fourth CIAM conference in 1933, which, due to the deteriorating political situation in Russia, took place on the bound for Athens from Marseilles. This conference is documented in a film commissioned by Sigfried Giedion and made by his friend László Moholy-Nagy "Architects' Congress." The Charter had a significant impact on urban planning after World War II and, thru Josep Lluis Sert and Paul Lester Wiener, especially on the proposed modernization of Havana. 
History.
Wiener joined José Luis Sert in 1942 to form Town Planning Associates which operated until 1959, when they finished the Havana Plan Piloto, as an architectural, urban planning, and site planning consultant firm. During this period, Wiener and Sert lectured in the United States and Latin America as experts in urban planning. 
Their designs exhibited elements of the “functional city” doctrine that Town Planning Associates promoted the Congrès Internationaux d'Architecture Moderne (CIAM), an organization founded by modern movement architects in 1928. The doctrine was codified in a document called the Athens Charter, drafted at CIAM's fourth meeting in 1933 in Greece. 
It also promoted ideas of GATEPAC (Grupo de Artistas y Técnicos Españoles Para la Arquitectura Contemporánea) the Spanish branch of C.I.A.M.
