It was the architect Robert Mallet-Stevens (1886–1945) who hit upon the idea of splitting a round tube in two and mitring the ends back together again at right angles. His creation is now known as the “Frankfurt model”. The handle was rediscovered when the Architecture Museum was built in Frankfurt and it proceeded to take the market by storm.
