Final answer:
Early 20th-century scholars, particularly from the University of Chicago, were responsible for naming and categorizing regional housing styles, as part of their work on understanding urban structures and their evolution.
Step-by-step explanation:
The naming and categorization of housing styles in various regions were generally the responsibility of early 20th-century scholars, including geographers, sociologists, and anthropologists. Many models were developed to describe the urban morphology and these included categorizations of housing styles. University of Chicago scholars, in particular, played a significant role during this time, as Chicago's rapid expansion in the previous century served as a fertile ground for developing such models to understand urban structures and their evolution. Folk housing, along with more planned housing projects like those in St. Louis and Chicago's Robert Taylor Homes, are examples of styles named and studied by such scholars. The variance in these projects and folk houses reflects a larger socio-economic and cultural narrative, including the impacts of the Industrial Revolution, legacies of discrimination, and regional adaptations to environmental conditions.
