Bruno Poucet’s professional career and academic work are intimately linked to Picardy, where he was born and raised. At the origins of a renewal of the history of education, he is also one of the instigators of a territorial approach (Amiens, the Somme département and more generally the Picardy region). The latter is the fruit both of his itinerary as a teacher and of an evolution in his research after having defended his HDR (Habilitation à diriger des recherches or Diploma enabling the directing of research), from the national to the local. This paper will examine this aspect of his contribution to research and its epistemological contribution. Three perspectives have been identified and contextualised. Poucet’s “taste for archives” led him to discover or invent local unpublished sources and to produce invaluable research guides or instruments. This practice accompanied the development of the history of higher education and of the Amiens académie or school district.
