This article reflects on the meaning of “public humanities” from the perspective of research and teaching in South Africa today. I reference the ways in which people have remembered the recently deceased Professor Eddie Webster (my first sociology professor) at the University of the Witwatersrand, and how he himself saw his critically engaged public work in the trade union movement and globally during both Apartheid and the post-Apartheid democratic government. In particular, I explore how his unique form of public humanities inspired his former students to be socially engaged citizens as they entered a diverse range of occupations and careers. I draw on Michael Burawoy’s depiction of the Webster windmill (public engagement, principled intervention, social justice and radical reform, expanding research programmes with a sociology of the south, and institution building) to suggest what public humanities means in the context of research and teaching. I draw on tributes from colleagues and former students – not to focus on Prof Webster’s significant academic and political work but to distil what it was about his teaching and critical engagement that suggests he is an exemplar of what is meant by public humanities.
