This book is in honour of the late sociologist Ken Plummer – a remarkable scholar whose work transformed several fields, from his early writing on symbolic interactionism, stigma, and sexualities, through methodological innovations that have underpinned the ‘narrative turn’, to his explorations of citizenship and humanism. The chapters in this collection cover a diverse range of topics, and all draw on Ken’s work, revealing his enduring and significant influence. The breadth of contributions here testifies to Ken Plummer’s impact across generations of scholars and sub-fields of sociology and social psychology. Many of the authors in this collection knew Ken personally, as colleagues, students, and friends. Contributing to debates on critical theory, intimacy, and sexuality, the interdisciplinary nature of this book enables it to reach a wide audience engaged in research methods, social theory, anthropology, media studies, sociology, psychology, and history. It is aimed primarily at students, lecturers, and researchers interested in gender, sexuality, identity, social history, social theory, research, and teaching methods.
