Sjoerd Keulen
Sjoerd Keulen was connected to Gies & Co. in his role as a merchant in foodstuffs and preserves.
Sjoerd Keulen married Lolkje Deinum on 10 May 1928 in Hemelumer Oldephaert en Noordwolde. On 25 April 1933 the court in Haarlem granted the dissolution of the marriage by divorce.[1]
In August 1937 Keilen established in Haarlem an import and export agency and commission business, which incorporated the manufacturing of foodstuffs. His business packaged foodstuffs, sold foodstuffs wholesale to retailers and produced peanut butter.[2] The telephone number of his company was 19360.[3]
During the 1948 investigation of the arrest of those hiding in the Secret Annex, Willem van Maaren referred to a certain Van Keulen from Haarlem as a supplier of preserves and instrumental in delivering supplies to Germans. Van Maaren was implying that this Van Keulen helped Gies & Co. make dubious deliveries to German institutions.
Sjoerd Keulen appears to be the only one in Haarlem who Van Maaren could mean. There is no further concrete data that suggests trade with Gies & Co. or with Germans.
