Located in from 1919–1924, the bauhaus was the german design school where ideas from all the advanced art and design movements were explored, combined, and applied to problems of functional design and machine production. workshops were taught both by an artist who focused on form, and a craftsman who focused on production. at first, the workshops were organized like medieval guilds—master, journeyman, and apprentice. the original slogan of the school, "a unity of art and handicraft," was later replaced by "art and technology, a new unity." a new seal designed by oscar schlemmer replaced the 1919 bauhaus seal, which is attributed to johannes auerbach.
