Arne Jacobsen had designed a house for H.J. Hansen, who was director of Lauritz Knudsen. Hansen was so enthusiastic about Jacobsen that he encouraged him to draw a clock back in 1939. The clock, which Arne Jacobsen designed back in 1939, was presented at the Spring Exhibition at Charlottenborg. It was the first of a total of four courses from Arne Jacobsen’s hand.
