 From the 1920s and after World War II, most of them either merged into universities or closed, although some continued until the 1970s.Students generally started at these schools from the ages of 16 to 20 years old, although sometimes as young as 14, and undertook a four-year course, in which they were given a general education and also learnt specific arts and craft skills such as weaving, metalwork, painting, sculpting, etc.Some of the most well known artists of the period had been Kunstgewerbeschule students, including Anni Albers, Peter Behrens, René Burri, Otto Dix, Horst P. Horst, Gustav Klimt, Oskar Kokoschka, Egon Schiele and Oskar Schlemmer.
