Introduction
This visual essay centres on a museum collection dedicated to the preservation of physical endings, both of a single life and across geological time. Johannes Weigelt (1890–1948), a German palaeontologist and geologist, was the first person to posit that to understand fossil formation in the ancient past, post-mortem processes should be examined in the present – an approach that would eventually become the field of taphonomy in current palaeontological research.Footnote 1 In the course of his professional career, Weigelt recovered dozens of fossil specimens and produced copious photographs that documented his fieldwork and laboratory analyses. These are currently stored at the Geiseltalmuseum, an institution founded by Weigelt in 1934 which remains in its original location to this day: a sixteenth-century chapel in downtown Halle (Saale), Germany. The exhibition hall still holds skeletons and other material under glass vitrines and in storage cabinets, some kept intact since the museum's inauguration. All of these are now part of the Central Repository of the Natural Science Collections at the Martin Luther University Halle-Wittenberg. Closed to the general public in 2011, the Geiseltalmuseum renewed limited visitor access in 2018 and serves as a working palaeontological collection to be accessed and used by scientists.
Weigelt's photographs have been the subject of less attention than has his specimen collection, scattered throughout different departments of the Martin Luther University Halle-Wittenberg. Those held at the Geiseltalmuseum include fieldwork documentation and publication plates, in addition to personal photographs that reveal Weigelt's entrenched ideological allegiance to the National Socialist German Worker's Party. Yet Weigelt's archive provided a surprising discovery in August 2016, when Dr Meinholf Hellmund (the late curator of the Geiseltalmuseum) and myself came upon over forty photo-collages in an uncatalogued box, presumably donated by his family decades after his death. Bearing a striking resemblance to works by Dada artists, the provenance of these previously unknown collages was unclear, as were the exact dates when they were created. However, several of the images incorporated in the collages indicate Weigelt as the maker, and suggest that these were produced during the early to mid-1930s, roughly the period when the Geiseltalmuseum was founded. Such timing is perplexing, both due to the work that Weigelt was putting into the creation of his museum and in light of his membership in the National Socialist Party. This fervent political affiliation would eventually account for the subsequent relegation of Weigelt's academic production from national and international circles after the Second World War.
Unusually for BJHS Themes, this is a visual essay in which the images and their collocations provide the argument. The medium of collage serves as a touchstone, allowing for the juxtaposition of photographs, documents and ephemera in the presentation of Weigelt across different stages of his academic career. Much like a collage, the collection of images and text presented here creates contrasts and disjunctions that question Weigelt's scholarly oeuvre. For example, how does one reconcile Weigelt's creative pursuits with the overarching Nazi condemnation of Dadaism during the Third Reich? What is revealed or concealed in this arrangement of photographs and printed matter, and the manner in which remnants of prehistoric epochs are combined with snapshots of a more recent past? And what was the ultimate motivation for Weigelt's collage making, in relation to both his academic writing and the expansive role of photography in his larger body of work?
These questions still await conclusive answers, as does analysis of the content and formal construction of these collages. But Weigelt's assemblages – fossils in the field, specimens in the museum, and photographs in the archive – offer the opportunity to reflect on how scientific collections come to an end, a concern that resonates with other contributions to this BJHS Themes issue. Indeed, taphonomy offers a broader conceptual framework from which to interpret German excavation sites, the Geiseltalmuseum and Weigelt's Nachlass (his collection of manuscripts, letters, notes and other documents). Here, taphonomy is not just a means to examine biological and geological traces in the fossil record, but also serves as a prompt for reflecting on the ideological evidence embedded in the exhibition and the private archive.
Frontispiece
In his 1927 monograph Recent Vertebrate Carcasses and Their Paleobiological Implications, Weigelt carried out a ‘full-scale research effort to document processes of vertebrate death, decay, disarticulation, transport, and burial’ as an attempt to understand fossil formation through ecological processes in the present.Footnote 2 Weigelt described this process as Biostratinomie – the earliest formulation of taphonomy, subsequently defined as such by Soviet palaeontologist and geologist Ivan Antonovitch Efremov in 1940.Footnote 3 The book features dozens of photographs of decomposing animals taken by Weigelt during fieldwork in the US Gulf Coast between 1924 and 1926. Weigelt drew parallels between these recent deaths and fossil specimens housed in the Martin Luther University Halle-Wittenberg, where he was university professor.
A central element of Weigelt's understanding of Biostratinomie was the concept of Leichenfelden, the German expression for ‘corpse fields’. Weigelt used this term throughout Recent Vertebrate Carcasses and Their Paleobiological Implications to describe large-animal carcass assemblages in the fossil record – sites where a combination of aquatic and geological depositional conditions allowed for the preservation of numerous intact specimens, if not entire ecosystems. Often animals would become trapped in the mud, dying in the same substrate that would later preserve their remains.Footnote 4 In addition to dead animals, Weigelt also photographed sites that he identified as potential Leichenfelden during his fieldwork in the US Gulf Coast, such as strandlines in swamps, flood areas, river meanders and other bodies of water, most notably Smithers Lake in Texas.Footnote 5 These contemporary locations provided a window for Weigelt onto how ancient ecologies came to be, while also merging biographic and historical information with his palaeontological explorations.
From the ground up
The Geiseltalmuseum was founded by Johannes Weigelt to showcase well-preserved fossils of Eocene fauna and flora recovered from the open-pit lignite mines in the Geiseltal valley of central Germany. Since its establishment in 1934, the museum has displayed mural paintings and diagrammatic reconstructions of ecosystems that date back over fifty million years. In several of his writings on Leichenfelden, Weigelt describes the biodiversity of Grube Cecilie, one of the main excavation sites of the Geiseltal, closed permanently in 1993 and filled with water to form the Geiseltalsee.Footnote 6 There are 125 species of vertebrate alone among the several thousand fossils that comprise the collection of the Geiseltalmuseum; many of these were recovered by Weigelt from the brown coal deposits, and are now displayed alongside those extracted by subsequent generations of palaeontologists from the same mines. Among the most renowned fossils are the Propalaeotherium specimens discovered during Weigelt's direction of the Geiseltalmuseum. Considered at the time to be the ancestor of the modern horse, Weigelt referred to these specimens as the Urpferd, which translates to ‘original horse’ or ‘proto-horse’. Specimens of Propalaeotherium remain one of the Geiseltalmuseum's renowned highlights today.
From 1934 onwards, the Geiseltalmuseum became a leading palaeontological institution in Germany – a progression aided by Weigelt's swift promotion from university professor (Professor ordinarius) to rector of the Martin Luther University Halle-Wittenberg. This advancement is largely attributed to Weigelt's fervent support of the National Socialist party during the Third Reich,Footnote 7 a fact Weigelt openly recognized in his public acceptance of this position.Footnote 8 Weigelt was known among his colleagues to coerce participation in the Nazi Party, in addition to unquestionably enforcing its discriminatory policies. Several testimonies by students and faculty from Jewish, Catholic and other marginalized backgrounds describe Weigelt's role in their removal from the Institute of Geology and Palaeontology, the precursor institution to the Geiseltalmuseum.Footnote 9 Weigelt served as director of the Geiseltalmuseum throughout his tenure as rector from 1936 to 1944.
Mining and unearthing
It is unclear exactly when Johannes Weigelt began creating photo-collages, but elements from these works place their appearance slightly before or during his tenure at the Geiseltalmuseum, matching the Nazi rise to power in Germany. If Weigelt did make them during the National Socialist period, he certainly would have been aware of the official Nazi position against Dadaism and all forms of avant-garde art, attacks that began in 1933 and lasted throughout the entirety of the Third Reich.Footnote 10 A precursor exhibition to Entartete Kunst, the infamous Nazi travelling exhibition of ‘degenerate art’, took place in the Kunstmuseum Moritzburg in January 1937 – only 350 metres away from the Geiseltalmuseum.Footnote 11 In fact, the Entartete Kunst exhibition itself was shown between 5 and 20 April 1941 at the Landesmuseum für Vorgeschischte, Halle's state museum for prehistory – a venue that surely would have been familiar to Johannes Weigelt.
Excavations at Grube Cecilie in the Geiseltal were suspended from 1939 until well after the end of the Second World War. During this time, Johannes Weigelt became an official geology adviser to ore extraction operations for Salzgitter AG in Lower Saxony, which was part of the Reichswerke Hermann Göring. Salzgitter AG was one of the largest mining operations for the Third Reich in Europe, producing millions of tons of steel and ammunition during the war through the forced labour of thousands of Jewish and other concentration camp prisoners.Footnote 12 It is unlikely Weigelt would not have been aware of the ubiquitous and deadly exploitation administered at the mining sites he regularly visited in this capacity.
Weigelt's cooperation with the Nazi Party led to his being awarded the Ritterkreuz des Kriegsverdienstkreuzes in 1945, the highest military honour for civilians during the Third Reich. This recognition, as well as his proximity to Göring specifically, flagged him to the Allies as a significant figure in Nazi circles. With the war over, on 24 June 1945, Weigelt was deported from Halle to Ober-Ramstadt in Hessen on board a train under US command due to his participation in the National Socialist Party. He was relocated to the Western Sector with other prominent Nazi scientists and intellectuals, such as biochemist and physiologist Emil Abderhalden, infamous for his ardent defence of eugenics.Footnote 13 Weigelt never occupied another academic position. He died a US prisoner of war in Klein-Gerau on 22 April 1948.
Post-closure
Johannes Weigelt's photo-collages leave viewers with more questions than answers. Their imagery freely intersperses reproductions of fossil specimens and technical shots from the Geiseltal mines with portraits of university colleagues and postcard scenes of Halle. Popular urban kitsch playfully slips into illustrations of scientific literature, as likely lifted from handbills on the street as from an academic monograph in Weigelt's private library.
It is uncertain whether Weigelt showed these works to anyone, or if in fact they were meant to circulate at all. Their production as composites in a darkroom is fairly self-evident; cut-out elements were arranged onto a square surface, subsequently photographed on film negatives, and then printed on photographic paper. The aesthetic decisions in bringing these elements together indicate that Weigelt had some familiarity with black-and-white photographic development processes, such as masking, burning and variable exposure. The collages also present Weigelt's strong sense of combinatorial experimentation, an element further underscored by the application of diverse photo-montage techniques and compositional inventiveness. However, there is no indication of where these collages were crafted, whether Weigelt benefited from any additional specialized assistance, or what was the ultimate purpose behind their making.
What Weigelt's enigmatic collages do provide is a re-examination of the Geiseltalmuseum as a Leichenfeld in itself – a site of salvaged and commingled remnants. Be it in their organic or their pictorial accumulation, fossilized and printed matter collapse disparate temporal elements, interpreted via archaeological extraction on the one hand and cut-and-paste reinterpretation on the other.Footnote 14 Similarly, the taphonomic processes of fossil creation – sealing and concealing, preserving and exposing – are analogous to the discontinuous history of the Geiseltalmuseum, with its openings and closures, as well as its prominent displays and its unknown findings. The collages and specimens at the Geiseltalmuseum, as well as the uncertainty of their present interpretation when read against Weigelt's academic and political life, offer a reminder that the meaning of a museum collection is never entirely settled, and, as such, cannot be said to fully conclude.
The words ‘collage’ and ‘collection’ stem from the Greek and Latin roots kólla, ‘to glue’, and colligere, ‘to gather.’ In Weigelt's oeuvre, fossils and pasted paper are fragmentary artefacts, both archaic and war-ridden in their disposition towards the viewer. Fascist inclinations, translated unambiguously in graphic and political allusions, do not escape Weigelt's scholarly and creative projects. Yet to understand the Geiseltalmuseum within the larger frame of taphonomy is to consider these ideological imprints as sites of hitherto unexplored connection – compounded layers of evidence related to mass extermination, both within the geological record and as a result of brutal human decimation from genocide and war.
