In honor of Amsterdam’s 750th jubilee and the 80th remembrance of the Netherlands’ liberation, Foam presents The Underground Camera (De Ondergedoken Camera). The exhibition showcases images captured by the group of photographers who came to be known by the same name. They photographed the harsh realities of Amsterdam during the ‘Hunger Winter’ of 1944-1945, offering a rare glimpse into the courageous missions of the resistance group and their role in documenting the Nazi occupation. The exhibition features work by renowned Dutch photographers such as Cas Oorthuys, Charles Breijer and Emmy Andriesse.

The resistance group was led by Fritz Kahlenberg and Tonny van Renterghem. In November 1944, when the German administration banned public photography, they – alongside a network of fourteen photographers – worked in secrecy to document the occupation and the resistance. Their efforts, carried out at great personal risk, preserved a crucial visual record of this era. Kahlenberg, a German Jewish filmmaker who had migrated to Amsterdam in 1933, was involved in the forgery of identity cards for the resistance. Van Renterghem had a military background and was also actively involved in resistance work. Although he was not a photographer himself, he played a crucial role in the coordination between The Underground Camera and other resistance groups. The images taken by the photographers of The Underground Camera were intended to be smuggled to London to convince the Dutch government in exile of the need for Allied food droppings in the Netherlands. Today, the photos provide a realistic perspective of daily life in Amsterdam during the last months of the German occupation.

The historical material of the group was stored in various Dutch collections in the form of negatives, original photo prints, albums and picture books. The exhibition sheds light on topics such as the Hunger Winter, the resistance, the illegal press, instances of sabotage, the transport of weapons and the liberation by the Allied Forces.

The Underground Camera is the result of a close collaboration with the NIOD Institute for War, Holocaust and Genocide Studies. A publication by the same name, written by NIOD-researchers René Kok and Erik Somers, will be released in March 2025. The exhibition has been co-curated by Hripsimé Visser, former curator of photography at Stedelijk Museum Amsterdam, in collaboration with designer Jeroen de Vries.

The Mayor of Amsterdam, Femke Halsema, will open the exhibition at Foam.
The exhibition is part of long-term thematic The Camera as a Weapon, in which Foam is committed to focusing on the role of photography in times of war and conflict.
In light of the national observance of Remembrance Day on 4 May and the national celebration of Liberation Day on 5 May, het Amsterdams 4 en 5 mei comité, in collaboration with Foam en NIOD, will also present an exhibition. This public exhibition will be shown from 29th of April until the 6th of May on the Museumplein.

About The Underground Camera

Kahlenberg and Van Renterghem, the driving forces behind the operation, instructed a group of photographers from their main location at the Michelangelostraat 36 in Amsterdam South from where they oversaw their resistance activities. Many of the The Underground Camera photographers would later become internationally renowned. They concealed their cameras in handbags and jackets in order for them to take the pictures unnoticed. Many used Rolleiflex cameras which had a viewfinder on top, making it easier to take pictures from hip height. Given the danger of being involved in organized resistance, the photographers did not know who else was part of the collective and worked under neutral names such as ‘Netherlands Archive’ (‘Nederlands Archief’) and ‘Central Imagery Archive’ (‘Centraal Beeldarchief’). Just a few weeks after the liberation, in early June 1945, a selection of work was showcased in the exhibition The Underground Camera located in the studio of the photographer Marius Meijboom at the Keizersgracht in Amsterdam. The exhibition brought national recognition for The Underground Camera’s work, leading the group to officially adopt this name. Now, 80 years later, their legacy returns in a new exhibition along the same canal.

The Underground Camera consisted of Tonny van Renterghem (1919-2009), Fritz Kahlenberg (1916-1996), Emmy Andriesse (1914-1953), Carel Blazer (1911-1980), Charles Breijer (1914-2011), Cornelis Holtzapffel (1916-1984), Ingeborg Kahlenberg-Wallheimer (1920-1996), Boris Kowadlo (1912-1959), Frits Lemaire (1921-2005), Marius Meijboom (1911-1998), Margreet Meijboom-van Konijnenburg (1910-onbekend), Cas Oorthuys (1908-1975), Hans Sibbelee (1915-2003), Ben Steenkamp (1917-1967), Ad Windig (1912-1996) and Krijn Taconis (1918-1979). Taconis was the first Dutch person to become a member of renowned international photography collective Magnum.
