The Bauhaus was an influential art and design school established in Germany in 1919. It aimed to combine craft, design, and technology to produce functional products on a mass scale. The school was founded by Walter Gropius and emphasized the philosophy of "form follows function," using minimal materials and simple designs. Notable Bauhaus teachers like Gropius, Breuer, and Mies van der Rohe later migrated to the United States and spread the International Style.
