The contentious science of phrenology once promised insight into character and intellect through external ‘reading’ of the head. In the transforming settler-colonial landscapes of nineteenth-century Australia and Aotearoa New Zealand, popular phrenologists — figures who often hailed from the margins — performed their science of touch and cranial jargon everywhere from mechanics’ institutions to public houses. In Science and Power in the Nineteenth-Century Tasman World: Popular Phrenology in Australia and Aotearoa New Zealand (Cambridge UP, 2023), Alexandra Roginski recounts a history of this everyday practice, exploring how it featured in the fates of people living in, and moving through, the Tasman World. Innovatively drawing on historical newspapers and a network of archives, she traces the careers of a diverse range of popular phrenologists and those they encountered. By analysing the actions at play in scientific episodes through ethnographic, social and cultural history, Roginski considers how this now-discredited science could, in its own day, yield fleeting power and advantage, even against a backdrop of large-scale dispossession and social brittleness.Piers Kelly is a linguistic anthropologist at the University of New England, Australia Learn more about your ad choices.
