His collection is composed of 55 framed photographic portraits of world-renowned dermatologists, sometimes dated and signed, as well as 47 acknowledgments and diplomas connected with his memberships in international dermatologic societies.

["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)]. / "Rohleder gehört zu den ersten, welche die Bedeutung der Sexualwissenschaft in ihrem vollen Umfange erkannt haben." : Leben und Werk des Venerologen, Urologen und Sexualmediziners Hermann Rohleder (1866­1934).

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.
