Lilly Reich (1885–1947) was a German architect and designer best known for her collaborations with Ludwig Mies van der Rohe, particularly in modernist furniture and exhibition design. She played a key role in designing the Barcelona Pavilion and the famous Barcelona Chair, pioneering minimalist, functional aesthetics. Reich was one of the first women to gain recognition in the Bauhaus movement, influencing interior and industrial design. Despite being overshadowed by Mies, her contributions to modernist materiality, spatial composition, and furniture innovation remain highly influential, shaping the evolution of 20th-century architecture and design.
