Reni Shulman Trüdinger (1927-2000) was born in Switzerland and worked as an interior architect, designing the Swiss Pavilion for the 1970 World Fair in Osaka. She worked with Charlotte Perriand early in her career. This modular system, used for sideboards and free-standing shelves, was designed in 1956 and produced by Wohnhilfe Zurich until 1959. Trüdinger married an American in 1959 and moved to Baltimore, Maryland, where she was involved in urban renovation projects. She opened her own interior architecture office in 1969 in Washington D.C. and designed the interior of the Washington Post building.
