Jean-Philip Mathieu is a PhD candidate at McGill University. His dissertation uses a case study of Montreal Rolling Mills, a major secondary iron and steel producer in the second half of the nineteenth century, to examine the relationship between the joint-stock corporation, the rise of Montreal's bourgeoisie, and the formation of the Canadian state. He argues that the joint-stock corporation consolidated wealth, but also consolidated the wealthy, and became a way for the city's capitalists to translate their economic power into social and political power, becoming by the early twentieth century the most influential group in the Dominion. More broadly, he is interested in the development of capitalism, labour history, and the history of the corporation. He is also passionate about the public history of Montreal, giving historical tours in non-pandemic years, and acting as a consultant for the Historic Sites and Monuments Board of Canada.
