Reforming Sex reconstructs the complicated history of a movement that has been romanticized as the harbinger of 1960s sexual radicalism and demonized as a precursor to Nazi racial policy, but mostly buried and obscured by Nazi bookburnings and repression. Relying on a broad range of sources--from police reports, films and personal interviews to sex manuals unearthed from library basements and secondhand bookstores--the book analyzes a remarkable mass mobilization during the turbulent and innovative Weimar years of doctors and laypeople for women''s right to abortion and public access to birth control and sex education.
