I'm a military historian wtih a background as museologist (collection information). I operate as an independent business as De Natris Erfgoedprojects and in combination with a partner as Maas+deNatris bureau for military history. I'm interested in security and society in the broadest sense, most notably in private initiative and private organisations working within society. I have worked for the Amsterdam Maritime Museum and the Rijksmuseum, amongst others. The last few years Stadsarchief Almere is the main supplier of orders.
