Jonas Kattenburg was a shoe wholesaler. He got his shoes from the 'Langstraat' (North-Brabamt) and sold them in Amsterdam to traders.
German business relations warned him for the threat of nazi Germany and advised him to flee to England. However, because of the strong family ties in Amsterdam this was not an option. When the Germans invaded the family tried to flee through the harbour in the Hoek van Holland, but they did not manage to get through all the traffic on the road. The two oldest children from this family survived the war by going into hiding with their partners.
