This article explores the biographical shaping of management theory. Using the British management theorist Lyndall Urwick (1891±1983) as a case study, it argues that existing understandings of the history of management studies are limited by their lack of attention to the emotional a priori of theory production. For men such as Frederick Taylor or Urwick, the work of composing management theory for a public audience was intimately connected to events and experiences in the private life. Theorizing addressed emotional dilemmas even while it strove to construct a separation between the personal and the organizational. Management theories are not only historically, socially or discursively constructed, but can be read in terms of the evidence they provide about individual subjectivity. Psychoanalytic concepts can help illuminate such relations. Theorizing can be seen as a form of play: as something which, in D.W. Winnicott's terms, takes place in the space between the psychic reality of the`me' and the external world of the`not me'. The`classical' administrative theory represented by Taylor, Fayol and Urwick sought to create organizational structures which could stand apart from, and allow the management of, individual personalities. It simultaneously insisted on the status of theory as the`not me'; that is, as a product which was not shaped by personal experience, but which constituted objective knowledge. The illusion of theory as a largely external, social product persists in much management and organization studies today. This article challenges that social determinism, first, by showing how Urwick's theories addressed issues of separation and intimacy, and second, by placing Urwick's work in the context of his relations with women.
