Photography has always played a significant role at documenta. Already at its first edition in 1955, a photo wall consisting of large-format portraits of the exhibited artists welcomed visitors into the entrance hall even before they could look upon the first works of art. Furthermore, visual documentations have been commissioned throughout documenta’s history from photographers, some of whom—such as Ernst Haacke or Balthasar Burkhard—even became renowned artists later on. However, it was not until 1977 that photography finally entered documenta as an independent art form. At documenta 6 (d-6), for the first and last time in the history of the periodic exhibition format, one section was dedicated entirely to photography. This marked a new era for the reception of the medium. In the wake of the revived photographic (exhibition) practices of the 1970s, the curatorial team, Klaus Honnef and Evelyn Weiss, who were also responsible for the painting section, devised an unorthodox concept. Instead of focusing on the recent developments in contemporary art, which was supposed to be documenta’s trademark, the curators combined photographic positions form the 1970s with historic masterpieces so that they would retell 150 years of the medium’s history. The reason for this highly discussed and controversial decision, which led to the resignation of several d-6 committee members, lay in the legitimization of new media entering the exhibition hegemony of documenta. Titled “Art in the Media World—Media in Art,” documenta 6 aimed to provide a far-reaching critique of media, a term used to replace the art genres, and a self-referential reflection on different concepts of mediality. This so-called “media-concept,” realized under the artistic direction of Manfred Schneckenburger, integrated, for the first time, not only photography but also film and video as independent sections. The concept of d-6 proposed that new media should be juxtaposed with more traditional art genres such as painting and sculpture. But only the photo section was underpinned by an historic narrative, while the sections of video and film focused strictly on contemporary practices, as had been documenta’s agenda since its founding. The following article tries to illustrate the motives behind what might at first sight seem like an inconsistent approach.
When photography was thrust into the limelight at documenta, very little elaborated historical or theoretical literature on photography existed. In a special issue accompanying d-6, Honnef and Weiss stated: “There is no doubt that not only a lack of information but also awareness has to be overcome, which goes beyond those of other media.”  The academic discourse on photography was still in its infancy, and most sources were only accessible through antiquarian bookshops. The curatorial team thus not only felt the need to make a representative selection of photography of the 1970s, but the necessity to integrate a visual historiography as a framework to which contemporary works could be linked. In addition to providing a historical revision, the photo section of d-6 also aimed at offering “a theoretical reappraisal of what [photography, M.S.] can achieve.”
Starting points for the conception of the d-6 photo section were the historiographies of Beaumont Newhall, former director and photo enthusiast at the Museum of Modern Art (MoMA), from 1949, and Helmut and Alison Gernsheim, German collectors and advocates of photography, from 1955, both published in the U.S. The selection of theoretical sources was even smaller: Walter Benjamin's today highly received photo-theoretical essays, “A Short History of Photography” (1931) and “The Work of Art in the Age of Mechanical Reproduction” (1935), had only been attracting the interest of art and media studies for a decade at that time, after the halt of academia during WWII. Apart from his writings, only photographer and theorist Gisèle Freund's dissertation, Photography and Society, written in 1932 and published in 1968, offered a theoretical framework for the conception of the photo section. After meeting Honnef in person in June 1975, Freund was not only exhibited at d-6 and taught a theoretical workshop in its supporting program, but also became one of the most important exchange partners for Honnef and Weiss, organizing visits to galleries and institutions in France and the U.S.
However, the photography section of d-6 cannot be understood as a “rehabilitation of photography,” as the curatorial team framed it. It was much rather a reaction to recent shifts in the art market, institutional collections, and photographic and curatorial practices starting from the late 1960s. For more than two decades, the exhibition programs of L. Fritz Gruber and Otto Steinert had already been reviving the photography scene of postwar Germany. While Gruber founded the international trade fair photokina in 1950, which had an extensive accompanying exhibition program, Steinert, teacher at Folkwang Hochschule design school in Essen, had delved into several decades of the medium’s history as well as various photo-theoretical discourses in his exhibitions at Museum Folkwang in the 1950s and 1960s. During the course of the 1970s, photography experienced a rise in representation and value in the art market, which led to the founding of a series of photo galleries across the Atlantic—from Light Gallery in New York (1971) to Galerie Wilde in Cologne (1972). The increased interest towards photography in the art market catalyzed photographic exhibition practices, enabling galleries to contribute an immense amount of expert knowledge, which many public art institutions were unable to provide. Honnef’s and Weiss’ ambitious project benefited from this new trend. For example, Galerie Wilde run by Ann and Jürgen Wilde was not only involved in d-6 as one of the major lenders, but also provided several contacts to international artists and wrote an astonishing 46 of the 146 essays, ergo the bulk of the accompanying catalogue.
At the same time, interest in photography worldwide on the part of art institutions increased. Examples include John Szarkowski's photography program at the MoMA that already progressed in the 1960s, as well as the opening of Centre Pompidou including its now renowned photography department in 1977. Many museums and libraries had only just begun to readdress their collections and archives. The Société française de photographie and the Bibliothèque nationale de France started to publish their first catalogues on their photographic collections starting at the end of the 1970s. Honnef and Weiss themselves had been curating exhibitions including photographic positions prior to d-6. While Weiss was a confidante of the collector couple Peter and Irene Ludwig, who collected photography from early on, and chief curator of 20th-century art at Wallraf-Richartz Museum, Cologne, Honnef curated the exhibition program at the Rheinisches Landesmuseum, Bonn, with a special focus on photography. Considering its large scale, prestigious state, and thus reach in the art world, the insertion of photography in the documenta format institutionally legitimized, on a whole new level, the medium as an independent art genre, part of the art(-historical) canon and, ultimately, academic discourses and curricula. Honnef and Weiss were well aware of the canonizing effects of documenta representation and thus of its power to shape narratives—an idea that was later elaborated by Walter Grasskamp, who labeled documenta a "model case for the production of art history" only one year after d-6. In a letter to Rolf Lucas, director of documenta GmbH at the time, the curators stressed: “While a presentation of the medium of drawing would be linked to an exhibition complex of an earlier documenta, and from this perspective, would provide a kind of historiography, a 'History of Photography' would be a completely new, but nevertheless long overdue undertaking.”
But what was stated here downplays the efforts of the previous edition of 1972, which paved the way for the inclusion of new media. As a result of the 1968 movement, a generation between disillusionment and new beginnings critically questioned and reexamined the canon of art, the position of traditional art institutions, and ultimately the self-image of artists. The notorious documenta 5 (d-5), for which Harald Szeemann was responsible, had already reacted to these developments. In addition to photographic media such as film and video installations, photographs were shown for the first time at d-5 in the context of sequential and conceptual works in the section Idee + Idee / Licht (Idea + Idea/Light ), for which Klaus Honnef had already been responsible in collaboration with German gallerist Konrad Fischer. To give an example, John Baldessari’s Ingres and Other Parables (1972), consisting of 20 sheets with text and photo, were on display at d-5.
Apart from this break from formerly fixed genres ultimately leading to the promotion of new media practices, the concept of d-5 is regarded to this day as groundbreaking in the history of the format. Not only did it establish the now indispensable thematic exhibition format of documenta, but it also fundamentally re-defined the role of the curator. Bremer describes this momentum as a “double rupture”—first, in the history of the institution, and second, in the history of exhibition-making in general. The hegemonic shift from an artistic to a curatorial authorship enabled Honnef and Weiss to achieve with d-6 to what museums and academia had not been able to provide: implementing photography as an autonomous art in exhibition practice as well as serious consideration as an integral part of art history. On top of that, the photo section has to be received as a testimony of the specific vision and agenda of Honnef and Weiss. As Evelyn Weiss stated in the exhibition catalogue, photography was to be examined within the norms of its own particular grammar without being tied back into a painterly tradition. This resulted in the intentional exclusion of important movements in the history of photography, like pictorialism, Bauhaus, and the influential figure Otto Steinert. Documentary photography, in the sense of an applied medium, instead became the guiding principle of Honnef’s and Weiss’ conception, which they framed as “direct photography.” The term mirrored Bernd und Hilla Becher’s artistic approach, who were the only photographers per definitionem on display at d-5, repeatedly shown at d-6 and whose approach became formative for an entire generation that followed.
As for the architectural and didactic concept, the curatorial team decided that the history and theory of photography should not be conveyed through long wall texts, but made “optically comprehensible” by means of an adroit, thematic arrangement of a series of images. In reference to the phenomenologically oriented media concept, 128 photographic positions were selected and hung very densely according to four systems of order: first, according to their historical context and thus in a chronological order; second, split into three subsections—“Direct Photography I,” “Direct Photography II,” and “Reflections and Expansion of the Medium”; third, within the subsections by topic-specific aspects such as “War” or “Fashion”; and fourth, within these aspects by individual artists. To give an example, Diane Arbus, who had previously been the first photographer to be exhibited at the Venice Biennale in 1972, was part of “Direct Photography II” and the subsection “Photographic Analyses and Comparative Presentations.” The artists were only assigned to a specific subsection in a given category. This stencil-like order is problematic, however. André Kertész, for example, was assigned solely to the category “City and Architecture”, whereas in the same year his solo show at the Centre Pompidou and Roland Barthes’ Camera Lucida in 1980 presented him as a portrait photographer. Just like Gisèle Freund, who fell under the category “Portraiture” at d-6, Kértesz had been photographing famous personalities such as the artist Piet Mondrian or the writer Tristan Tzara. On top of that, photographic positions within the same categories were not mixed, which could have made points of reference between one individual photographer and another visible.
In the end, the original concept of d-6 to juxtapose different media had to be abandoned due to limited space capacities. The curators tried to tackle this by adding an additional floor on the first level of the Fridericianum, documenta’s core exhibition space (fig.10), but a large part of the contemporary pieces of the photo section eventually had to be transferred to the Neue Galerie and thus excluded from documenta’s main exhibition space. This unintended move, which could not be documented in the exhibition’s catalogue, but which can be retraced through correspondence and installation shots, interrupted the whole narrative and didactic concept of the photography section. The result was an emphasis on the historization of the medium, rather than a dialogue with contemporary practices and other media.
The final display, framing photography in the form of a visual historiography, was not received as a successful solution, also due to the limited, thus overcrowded, space. Moreover, journalist Wilfried Wienand criticized the detachment of the photographs from their historical context and original displays, which he felt reflected a concession to the art market, as follows: “To exorcise the history of the photo and reduce it to the mere image may be an appropriate practice for the art market, which displays the photo like a graphic, but for the interpreter it is barbarism. Unfortunately, this was practiced in Kassel, where most photos were squeezed under egalitarian passe-partouts and in frames that seem so faceless and ahistorical that they could have been omitted.” What nevertheless has to be acknowledged is the fact that photography still turned out to be integrated into every level of Fridericianum—from Ger Dekkers’ Planned Landscapes (1974–1977) on the first floor, to Braco Dimitrijević’s This Could Be a Place of Historical Interest (1976) right under the roof of the rotunda. The extensive share of photography at d-6 also manifested in written form. Not only did the photography section have the biggest coverage in the accompanying new media catalogue, fotografie. film. video, but it was additionally documented in four special editions of Kunstforum International, edited by Honnef himself and partly published even before the opening of d-6. The bold approach of Honnef and Weiss was a crucial moment for the institutionalization of photography. Today, the photo section of documenta 6 is considered a milestone in the history of photographic exhibition practice and often received as a starting point that, as this article has shown, has to be perceived as the culmination of photographic practices and exhibitions in the 1970s.
Mona Schubert is a photo researcher and curator, and has been assistant curator at Fotomuseum Winterthur since 2019, where she co-curates the experimental, curatorial format SITUATIONS, exploring networked image practices and reframing the idea of exhibitions in relation to new technologies. Prior to joining Fotomuseum, she was a student assistant from 2013 to 2018 for Herta Wolf, professor for history and theory of photography at the University of Cologne, where Schubert is a PhD candidate working on the topic “(Re-)construction of a Medium. Photography at documenta 6.” She studied art history as well as German language and literature in Cologne and Budapest and was part of the Research Master Programme of the a.r.t.e.s. Graduate School for the Humanities Cologne. Her research on photography is situated at the intersection of art history, history of technology, and media history with a special focus on photographic practices and exhibitions after 1945, as well as gender-related issues in the context of the networked image.

 This essay is based on my research that began in the Research Master program of the a.r.t.e.s. Graduate School for the Humanities Cologne in 2017, leading to my current PhD project, “(Re-)construction of a Medium. Photography at documenta 6,” under the supervision of Prof. Dr. Herta Wolf, History and Theory of Photography, Institute for Art History, University of Cologne. My dissertation will not only be the first critical study of the photography section of documenta 6, but also the first reconstruction of its display on the basis of the archival materials held at the documenta archiv in Kassel and ZADIK in Cologne.
