This article pursues the hypothesis that there is a structural affinity between the case study as a genre of writing and the question of gendered subjectivity. With John Forrester’s chapter ‘Inventing Gender Identity: The Case of Agnes’ as my starting point, I ask how the case of ‘Agnes’ continues to inform our understanding of different disciplinary approaches to theorizing gender. I establish a conversation between distinct, psychoanalytically informed feminisms to move from the mid-20th century to contemporary cultural debate.
