Drawing on historical data largely relating to Price Waterhouse Coopers (PwC), this article examines the early professionalisation of accountancy as a gendered process. Mobilising Acker's (1990) theory of the ideal worker, this article highlights articulations of an ideal professional accountant, coded as male and masculine in the gendering of professional skills and knowledge, image management, networking and social class. Additionally, social changes such as WW1 reshaped the masculine nature of the ideal professional accountant in PwC, emphasising a militaristic masculinity, to support the war effort. While women were temporarily employed in accountancy clerical jobs in wartime, this does not appear to have regendered PwC as an organisation inclusive of femininity and women. However, it is noted that some middle-class women challenged exclusionary professional practices within accountancy.The implications of the gendered aspects of the professionalisation of accountancy are discussed throughout the article.
