Argentine architect Amancio Williams (1913–1989) initially studied engineering, then worked in aviation, and later completed his architecture degree at the Universidad de Buenos Aires in 1941. Throughout his career, he undertook a wide range of projects—monuments, residential, office, and industrial buildings, as well as interiors, furniture, object design, and large-scale urban developments. His early works included Viviendas en el espacio (1942), Estudio para viviendas en Casa Amarilla (1942–43), Sala para el espectáculo plástico y el sonido en el espacio (1942–53), Una nueva bóveda cáscara (1951–52), and the celebrated Casa sobre el arroyo in Mar del Plata (1943–45). In 1949, Williams collaborated with Le Corbusier on Casa Curutchet in La Plata and also submitted government proposals, including an international airport and hospitals for Corrientes Province. His career combined realized works with structural innovations and visionary urban schemes such as La ciudad que necesita la humanidad (1952–73) and was recognized through invitations to exhibit internationally. Williams was named an honorary member of the American Institute of Architects (1962) and Argentina’s Academia Nacional de Bellas Artes (1982).
