Peter Townsend, who sadly passed away in June 2009, had a long career researching an exceptional range of topics within the social sciences and campaigning against social inequalities. This reader brings together for the first time a collection of his most distinctive work, allowing readers to review changes and continuities over the past six decades, and reflect on social issues that have returned to the fore today. A particular feature of the volume is in tracing the links between empirical evidence and both social theory and social policy, and how those disciplines intersect. This reader will provide a teaching and learning resource for students in different disciplines of the social sciences and will also provide an insight into the development of one scientist’s entire intellectual approach. We hope it will be a fitting memorial to his life and work.
