In the 1920s, Robert Mallet-Stevens mitred two sections of tubing together to create the FSB 1076. Ludwig Wittgenstein bent brass tubing for the FSB 1147. And Walter Gropius and Adolf Meyer married an angled spindle to a handle bushing to produce the FSB 1102. But to this day we still don’t know who it was that picked up a saw and ‘liberated’ the FSB 1147 from its hemispherical tip.
