Barrie Blatchford (2022-2023 Eugene Garfield Fellow) is a historian of American environmental history with a focus on the nineteenth and twentieth centuries. He holds a BA (Hons) and MA in History from the University of British Columbia, and an MPhil from Columbia University. His dissertation, provisionally entitled “Unnatural Selection,” analyzes animal “acclimatization” – the intentional introduction of non-indigenous species – in America from the late nineteenth century through to the mid-twentieth. It argues that historians have failed to appreciate the magnitude of animal acclimatization, as well as the civilizational, nation-building terms in which Americans understood it.
