Jane Addams stands as perhaps one of the most prominent female voices in social theory of the late 19th and early 20th centuries. While built through books, essays, journal articles, and speeches, her intellectual legacy has seldom been recognized as academic by contemporary audiences. Yet, over the last forty years, her contributions to sociology, philosophy, conceptions of democracy, inquiry, feminism, care ethics, community engagement, social ethics, community engagement, peace, municipal governance, social justice, and more have emerged and received traction in the scholarly literature. The Oxford Handbook of Jane Addams is a selective collection of original analyses offered by an international group of social and political theorists who have contributed to the burgeoning field of Addams Studies.This Handbook is a testament to the maturity of contemporary Jane Addams studies. Less than a half-century ago, such a scholarly collection would have been considered unwarranted. Despite intellectually influencing her contemporaries, Addams was marginalized as an original thinker for much of the 20th century. Today, a resurgence of academic work led by feminist scholars such as Mary Jo Deegan and Charlene Haddock Seigfried has restored Addams to her rightful place as an essential intellectual pioneer with ongoing significance. This collection pays particular attention to her contributions to scholarly fields of sociology and philosophy as well as to more professional disciplines of public administration and social work. Furthermore, this volume signifies Addams's global impact as scholars from all over the world contribute to the tapestry of her intellectual legacy. The 38 chapters in this volume are divided into six sections: Addams, Democracy and Social Theory; Addams and Her Contemporaries; Addams Across Disciplines; Addams, Peace and International Relations; Addams on Knowledge and Methods; and Addams and Social Practice. A major focus of The Oxford Handbook of Jane Addams is how Addams's insights remain relevant when confronting today's social challenges.
