This is the first full-length biography of Richard Titmuss, a pioneer of social policy research and an influential figure in Britain’s post-war welfare debates.Drawing on his own papers, publications, and interviews with those who knew him, the book discusses Titmuss s ideas, particularly those around the principles of altruism and social solidarity, as well as his role in policy and academic networks at home and overseas. It is an enlightening portrait of a man who deepened our understanding of social problems as well as the policies that respond most effectively to them.
