ABSTRACT Are journalists born or made? During the interwar period (1919–1939), the British National Union of Journalists (NUJ) grappled with this question, as the first university course for journalism was founded and more university-educated staff entered newsrooms. This article is the first to consider interwar journalists’ opinions on whether and how British journalists should be educated. Debates on journalism education continued until the 1990s, when university education became the norm for British journalists. This article explores the emergence of this contentious argument. Through the articles published in the pages of the NUJ’s monthly member magazine the Journalist, two strands of the NUJ’s activities on education are explored: the Union’s stance on the University of London Diploma for Journalism and the work of the NUJ’s Education Committee. During the interwar period, the National Union of Journalists developed educational output for its members. Unlike other British trade unions, the NUJ focused on providing its members with education that was directly related to their careers. These activities raised fundamental questions that went to the heart of the profession during a period when journalism’s professional identity in Britain was still evolving.
