This innovative study examines the development of institutional childcare from 1878 to 1929, based on a comparison of two "sister" orphanages in Pittsburgh: the all-white United Presbyterian Orphan's Home and the all-black Home for Colored Children. Drawing on quantitative analysis of the records of more than 1,500 children living at the two orphanages, as well as census data, city logs, and contemporary social science surveys, this study raises new questions about the role of childcare in constructing and perpetrating social inequality in the United States.
