How has gay interest politics changed since the founding of the Scientific-Humanitarian Committee in 1897? What transformed the organizational process of homosexuals into a social movement, and who were its actors? What goals were pursued, what means did the activists employ, and what was achieved? What topics sparked internal controversies? How do we evaluate the different forms of movements and political designs today? After the first four volumes on the history of homosexuals in post-war Germany focused on eyewitness accounts, scholars now take the floor. This anthology includes contributions from Claudia Bruns, Jens Dobler, Norman Domeier, Sigmar Fischer, Michael Holy, Georg Klauda, Kirsten Plötz, Stefan Micheler, Heike Schader, and Volker Woltersdorff.
