[Urology and Sexology in Berlin 1880-1933: Original citations for the establishment of this frontier of urology - protagonists as reflected in their publications]

[Early origins of a physician specializing in sexual medicine from the urological perspective : Max Marcuse (1877-1963)-"physician for skin and urinary diseases"]

The development of sexual medicine starts in Europe in parallel to the evolving clinical specialties urology, venerology, gynecology, neurology/psychiatry, and internal medicine at the end of the 19th century in Berlin. For this reason, we find many examples of fruitful collaboration but also in segregation from each other in defining the new specialties. Max Marcuse, the only one of the well-known Berlin specialists Ivan Bloch, Magnus Hirschfeld, and Albert Moll to survive the Holocaust, was able to publish articles in Palestine and Israel from the 1930s to the 1960s. This year is the 60th anniversary of his death.

[Why in Koenigsberg, why Samuel Jessner, why 1921? : History of the first university lectureship for sexology in Germany]

The dermatologist and venerologist Samuel Jessner (1895-1929) received a lectureship for sexology at the University of Koenigsberg (today: Russian Калининград, Kaliningrad) in 1921. Since 1928 he was also listed as a urologist in the Reichsmedizinalkalender (German Physician Address Calendar). In this article we trace his life and work and ask how Jessner was able to achieve this academic success in the periphery of German sexology and without close ties to its networks. His weak influence in research, his lack of connection to a "school" of sexual science in German-speaking countries, and his Jewish origin were factors that impaired both the recognition of his work among his contemporaries and his recognition in the discipline-specific historiography until today.

["Rohleder was one of the first to fully realize the importance of sexology." : Life and work of the venereologist, urologist, and sexologist Hermann Rohleder (1866-1934)]

His contemporaries described Hermann Rohleder, a physician from Leipzig, as a pioneer of sexual medicine. His career led him from treating patients with venereal diseases to urology and sexology. Rohleder worked for the institutionalization of sexology in Germany, but his attempts to establish a professorship at the University of Leipzig remained unsuccessful. Rohleder's life and work illustrate how closely the disciplines of urology and sexology were connected in the early 20th century.

[Urology goes electric-electrotherapy : Modern therapies in the treatment of modern diseases-examples from urology]

The significance of electricity for medicine in the modern industrial age should not be underestimated. Particularly in connection with neurasthenia, electrotherapeutic approaches also experienced a boom for domestic use. Thus, electrotherapy reached urology just as it was becoming established as a medical specialty. We analyzed urological manuals and textbooks and objects in the W. P. Didusch Center for Urologic History and the Museum zur Geschichte der Urologie in Berlin to present the wide range of indications for electrotherapy in the emerging field of urology from impotence to urethral strictures and try to highlight the variability of their importance over time.

[Carl Posner (1854-1928) : A founder of urology and sexology in Germany]

In this contribution we describe the life and work of the Berlin physician Carl Posner (1854-1928). We present his central role as a member of the founding generation of urology, andrology, and academic sexology in Germany. His clinical work, research and publication illustrate the central role these new disciplines played in the urological field. Finally, we describe how Posner is remembered in the history of urology and sexology.
