This article seeks to exemplify the extent to which oral life history research can enrich existing historiographies of English Religious Education (RE). Findings are reported from interviews undertaken with a sample of key informants involved in designing and/or implementing significant curriculum changes in RE in the 1960s and 1970s. The interviews provided insights into personal narratives and biographies that have been marginal to, or excluded from, the historical record. Thematic analysis of the oral life histories opened a window into the world of RE, specifically in relation to professional identity and practice, curriculum development and professional organisations, thereby exposing the operational dynamics of RE at an (inter-)personal and organisational level. The findings are framed by a series of methodological reflections. Overall, oral life histories are shown to be capable of revealing that which was previously hidden and which can be confirmed and contrasted with knowledge gleaned from primary documentary sources.
