The first sentence of this text summarizes what will be addressed in this article: “What connections can be imagined between erudition, urban vandals who deface the city with graffiti, the biographies of Henri Poincaré and Albert Einstein, and the construction of heritages and e-heritages?” This article assesses the new forms of erudition that have been made possible by information and communication technology (ICT) and communication studies. We hope that this will encourage more research to be undertaken on the history of the media and of archives (whether personal or official), so that their countless aspects, breadth, and importance to many fields of knowledge will be more fully appreciated. Of particular interest is the form that, in collaboration with Jean-Marc Ginoux, we have identified and named as the “pop history of science.”
