The Pioneers of Social Research, 1996–2018 is a rich qualitative collection of life story interviews with over fifty pioneering academics, who are regarded as having played a significant role in developing the practices of social research across key disciplines. The project was directed by Paul Thompson, himself a pioneer of oral history in Europe. The interviewees are essentially British pioneers, all but six born within what was then the British Empire, but they worked worldwide in Europe, Africa, Australasia, the Caribbean, Latin America and the United States. The collection includes full interview transcripts and detailed summaries, YouTube playlists, thematic highlights and associated teaching resources, all openly accessible through the UK Data Service. The following data paper provides an overview of Thompson’s data collection approach, the archiving and publishing of the data materials, and a discussion of the resources available. It also highlights opportunities of this unique research data for future use.
