Who developed the Bauhaus Vorkurs preliminary course?

The Vorkurs, or preliminary course, at the Bauhaus was developed by the Swiss painter and sculptor Johannes Itten.1

This introductory course, which became the most widely copied aspect of the Bauhaus curriculum, required students to explore two- and three-dimensional design using simple materials like wire, wood, and paper, while also studying the psychological effects of form, colour, and texture. While Itten was the primary developer of the course, the six-month preliminary requirement was later taught by other notable faculty members, including Josef Albers and László Moholy-Nagy.12
