How the Suburbs Were Segregated
by Paige Glotzer

The Roland Park Company, which developed Baltimore’s wealthiest, whitest neighborhoods starting in the 1890s, had by the middle of the twentieth century an outsize influence on real estate professionals and on local and federal housing policy. Historian Paige Glotzer examines how racial exclusion structured the U.S. housing market.

Paige Glotzer is Assistant Professor and John W. and Jeanne M. Rowe Chair in the History of American Politics, Institutions, and Political Economy in the University of Wisconsin-Madison Department of History. Her first book, How the Suburbs Were Segregated: Developers and the Business of Exclusionary Housing, 1890-1960, charts how suburban developers, including Baltimore’s Roland Park Company, ushered in modern American housing segregation with the help of financiers, real estate institutions, and public policymakers. Her work has appeared in both peer reviewed journals and in publications for a general readership, including the Journal of Urban History, Time, CityLab, and the Baltimore Sun. Paige’s primary research focuses on the financing, production, and maintenance of segregated spaces in the United States although she is also increasingly interested in transnational urban history. In addition to her research, she is interested in working to make academic spaces more accessible and equitable.
