César Janello sketched the first versions of his iron-frame “W” Chair after seeing the BKF butterfly chair in 1944. In 1951, pictures of the “W” Chair were published in the Argentinian art magazine, Nueva Vision, bringing the design to a huge market. The “W” Chair is now Janello’s most recognizable work because it was used by Le Corbusier in his design for the private home of the surgeon Dr. Pedro Domingo Curutchet in La Plata, Argentina in 1953. The construction of Maison Curutchet, Le Corbusier’s only South American project, was supervised by Amancio Williams, an Argentine architect who helped to promote Janello’s furniture throughout the 1940s and 1950s.
