Hannes Harms Scum Stool
Probably Hanes Harms, a German industrial designer who graduated from Wuppertal and the Lodon Royal Academy of Art doesn’t want to be remembered as the designer of the Scum Stool…What’s in a name? I’ll tell you:Both in German Schaum and in Dutch Schuim have several alike meanings : Foam and Scum. Hence the name I presume.
