In 1963 Horst Brüning set up an architecture and design office in Stuttgart. During this period, Brüning came in contact with Kill International and the architect duo Fabricius & Kastholm, involving a successful exchange of ideas, which in the end led to international recognition and success. It was in this period the late 60’s the HB 6910 Series was designed. Brüning and Fabricius & Kastholm’s designs were originally manufactured by the same company, and have today been resumed by Lange Production to continue this original idea.
