William A. Henkin

United States · 1947–2018

William A. Henkin was an American educator, author, lecturer, activist, and one of the earliest public advocates for consensual BDSM education in the United States. Trained as both an educator and therapist, Henkin devoted much of his career to promoting accurate information about consensual sadomasochism at a time when reliable educational resources remained scarce and public understanding was largely shaped by stigma, sensationalism, and psychiatric misconceptions. Henkin became widely recognised through his work with the National Coalition for Sexual Freedom (NCSF), the Society of Janus, and numerous educational organisations within the Leather and BDSM communities. Throughout the 1980s and 1990s he presented workshops, lectures, and public discussions on negotiation, consent, communication, relationships, and responsible BDSM practice, helping to establish educational standards that would later become commonplace within community organisations. Together with Sybil Holiday, Henkin co-authored *Consensual Sadomasochism: How to Talk About It and How to Do It Safely*, one of the broadest educational surveys of BDSM published during the formative years of the modern community. Rather than concentrating exclusively on techniques, the book presents BDSM as a complete culture founded upon informed consent, communication, ethics, safety, and mutual responsibility. It remains one of the landmark educational references of its generation. Henkin's writing consistently reflects a community-centred philosophy. He viewed education not merely as the transmission of technical skills, but as the cultivation of ethical judgement, interpersonal communication, and personal responsibility. His work encouraged practitioners to participate actively in building safe, respectful, and supportive communities while recognising BDSM as a legitimate form of consensual adult expression. Within The Library of The Cellars, William A. Henkin is preserved as one of the pioneering educators who helped transform BDSM from a largely private subculture into a community capable of educating itself through shared knowledge, responsible practice, and open dialogue. His contribution lies not only in the information he documented, but in the educational culture he helped create.
