Beginning in the 1880s, the modern foundations for architecture as a profession and academic discipline were established in Latin America’s major cities. Soon thereafter, urban planning (urbanismo) began to emerge as a distinct discipline in a period of scientific and technological innovation. This rich history has been compiled, digitized, and made available to the public by two key institutions: the Facultad de Arquitectura of the Universidad Nacional Autónoma de México (FA-UNAM) in Mexico and the Facultad de Arquitectura, Diseño y Urbanismo of the Universidad de Buenos Aires in Argentina (FADU). Collectively, these two digital projects contain a wealth of information for scholars to research the cultural and intellectual histories of cities in both Argentina and Mexico. The primary resources available on both platforms provide valuable insights into how Latin America’s leading architects and planners analyzed, debated, and envisioned urban life in the 20th century.
