This edited volume highlights the work of ten forgotten and neglected social theorists in the hope of reinvigorating interest in their work and their potential contributions to the analysis of contemporary social issues. Each chapter includes a brief biographical sketch, an overview of the selected theorist's work and significance, and the relevance of their work to one or more contemporary social issues. While other similar texts tend to focus primarily on intellectual biography, our emphasis here is on the scholar's theories and their application to contemporary social issues. We provide a contextualization of each scholar's work, using present-day social issues or problems. Many of these individuals played a significant role in the development of sociology. Our hope is to provide a resource that will help re-integrate these marginalized social theorists, rescuing them from obscurity and elevating their status.
