In the decades before the First World War, Europeans developed new institutions and information networks to try to understand and manage a rapidly changing world economy. This was a diffuse organizational web without a clear institutional centre, but it was grounded in an increasingly standardized and professionalized set of treaty practices. This chapter traces Lucien Coquet, Hubert Llewellyn Smith, Bernhard Harms, and Richard Riedl as they began to build careers in a globalizing economy that was marked by sharp social and political tensions.
