The history of the relationships between social work, social reform, social policy and social science contains an important story about the contributions of men and women, and about the ways in which masculinist social science and policy came to dominate the activities of women reformers and social scientists. This article focuses on a moment in this history, a conflict at the London School of Economics (LSE) in the 1950s about the future of social work education. A key figure in this was the author's father, Richard Titmuss. The article draws on biography, autobiography and intellectual/institutional history, raising some methodological issues about this approach to uncovering hidden stories; it also argues that the conflict at LSE, a painfully remembered episode in the history of social work, cannot be understood except in the context of the gendered story of 'the socials'.
