Photo Lessons: Teaching Physiognomy during the Weimar Republic

Photography flourished during the Weimar Republic as a prolific form of visual communication. Artists were remarkably aware of their era as a moment of transition in which an imagined future of a new photographic language was yet to occur. In a photographically illustrated essay published in 1928, the graphic designer Johannes Molzahn envisioned a future in which reading would be an obsolete skill. ‘ “Stop reading! Look!” will be the motto in education, ’ Molzahn wrote, ‘ “Stop Reading! Look!..

Photography in the Third Reich

This lucid and comprehensive collection of essays by an international group of scholars constitutes a photo-historical survey of select photographers who embraced National Socialism during the Third Reich. These photographers developed and implemented physiognomic and ethnographic photography, and, through a Selbstgleichschaltung (a self-co-ordination with the regime), continued to practice as photographers throughout the twelve years of the Third Reich. The volume explores, through photographic reproductions and accompanying analysis, diverse aspects of photography during the Third Reich, ranging from the influence of Modernism, the qualitative effect of propaganda photography, and the utilisation of technology such as colour film, to the photograph as ideological metaphor. With an emphasis on the idealised representation of the German body and the role of physiognomy within this representation, the book examines how select photographers created and developed a visual myth of the ’master race’ and its antitheses under the auspices of the Nationalist Socialist state. Photography in the Third Reich approaches its historical source photographs as material culture, examining their production, construction and proliferation. This detailed and informative text will be a valuable resource not only to historians studying the Third Reich, but to scholars and students of film, history of art, politics, media studies, cultural studies and holocaust studies. As with all Open Book publications, this entire book is available to read for free on the publisher’s website.

Posttranscriptional stimulation of endothelial cell matrix metalloproteinases 2 and 1 by endothelioma cells

Matrix metalloproteinases (MMPs) play a critical role in the development of hemangioma-like vascular tumors in mice injected with murine eEnd.1 endothelioma cells. The current study was designed to (a) characterize the presence of MMPs in the vascular tumor, (b) define whether these MMPs originate from the transformed cells or from the recruited stromal cells and (c) study the stimulatory effect of eEnd.1 cells on the production of MMPs by endothelial cells. Several gelatinases were present in the eEnd.1 tumor extract, including latent and activated MMP-2 (72-kDa gelatinase A, EC 3.4.24. 24) and MMP-9 (92-kDa gelatinase B, EC 3.4.24.35). Immunohistochemical analysis of the tumor revealed focal reactivity for MMP-2. No gelatinase was produced by cultured eEnd.1 cells, or by six of nine related endothelioma cell lines, suggesting that stroma cells, particularly endothelial cells recruited by the tumor cells, rather than eEnd.1 cells themselves, are the source of the gelatinases observed in the tumors in vivo. The conditioned medium of eEnd.1 cells stimulated the release of MMP-2 and MMP-1 (interstitial collagenase, EC 3.4.24.7) by endothelial cells, but not of the inhibitor TIMP-2. The increased production of MMP-2 and MMP-1, observed at the protein level (zymogram and Western blot analysis), occurred through a posttranscriptional mechanism, since no increase in mRNA was observed and the stimulation was not prevented by inhibitors of protein synthesis. The inhibitory effects of monensin and brefeldin A, inhibitors of protein secretion, and the decrease in cell-associated MMP-2 in stimulated endothelial cells indicated that regulation occurred mostly at the level of protease secretion. MMPs are known to be regulated at different levels; this study indicates that, in endothelial cells, the stimulation of MMPs can also occur at the level of secretion, a mechanism that provides a rapid mobilization of these crucial enzymes in the early phases of angiogenesis
