Obituary and call for testimonies
It is with deep sadness that the International Society for Cultural-historical Activity Research announces the passing of Oxford Emeritus Professor Harry Daniels.
Harry was an active contributor to ISCAR, an organization and community he helped shape with integrity and dedication. He served as ISCAR board member for two consecutive terms, starting from 2002—the year ISCAR was established—to 2008.
His work sits at and advances the intersection of sociocultural and cultural-historical activity theory (CHAT), Vygotskian psychology, and the sociology of education.
Before joining the Department of Education at University of Oxford, he held Chairs at the Universities of Bath and Birmingham, as well as international appointments at Griffith University, Kansai University, and Moscow State University of Psychology and Education. His most noted books include Vygotsky and Pedagogy, Vygotsky and Research, and The Cambridge Companion to Vygotsky, alongside influential work engaging Basil Bernstein’s sociology of pedagogy. Over his career he directed numerous funded research projects on topics ranging from school exclusion and mental health in schools to school design and the use of drama in education.
It has been shocking to learn that this titan of our research community has left us. His passing behooves us to reflect on his contribution to both our understanding and use of theory and how his work has made the world a better place. It is his lifelong commitment to the most disadvantaged students in our schools and making a difference to their learning that ISCAR holds as a touchstone for so many in their own work. Looking back over his work, we realize how much of it has been foundational to ISCAR community members’ understanding and practice, how many of us were introduced to Vygotsky by his writing and speaking, and then how much of it we have yet to explore.
Harry was unfailingly generous in supporting doctoral and early career researchers around the world. Many of us during the consolidating phases of our academic paths could always count on him for sound advice and insightful comments in critical phases in their work.
Harry will be remembered as one of the field’s most influential figures in applying Vygotsky’s ideas to educational practice and policy. By bringing together the Vygotskian legacy and Basil Bernstein’s work, he reshaped empirical research on mediation and the social formation of mind.
Professor Joanne Hardman at the School of Education, University of Cape Town, is gathering memorial testimonies for Harry’s partner, Jill Porter, and the family. Those who want to contribute are welcome to send emails Jo Hardman at joanne.hardman@uct.ac.za
Losing Harry strengthens our resolve to continue his legacy with our own students and constructive interactions among colleagues. On the occasion of ISCAR’s triennial congress in Cape Town, South Africa, in August 2027, a special session is being planned on his work and legacy. That Harry’s work will drive future development and practice through his students, writings and recordings consoles us.
Thank you, Harry Daniels.
