In March 2020, Melvin Richter, one of the founders of international, conceptual history passed away. This sad occasion makes it timely in our journal to reflect on the process that turned national projects within conceptual and intellectual history into an international and transnational enterprise. The text that follows—published in two parts, here and in the next issue—takes a closer look at the intellectual processes that led up to the founding meeting of the association behind our journal, the History of Concepts Group. It follows in the footsteps of Melvin Richter to examine the different encounters, debates and protagonists in the story of international, conceptual history. The text traces the different approaches that were brought to the fore and particularly looks at Melvin Richter’s efforts to bridge between an Anglophone tradition of intellectual history and a German tradition of Begriffsgeschichte.
