American Higher

The era after World War II saw America's urban planners treat the lives of city-dwellers with disdain. It spawned a philosophy of urban renewal that valued the efficient movement of cars more than it valued the lives of people, and that wiped out entire neighborhoods dismissed by bureaucrats as slums. Published in 1961, Jane Jacobs's The Death and Life of Great American Cities examines the shortsightedness and failure of this philosophy. The book turns away from strict statistical study and abstract planning theory in favor of observations.

It was the vast frontier stretching out to the west of the developed land on the North American continent that shaped the American character - and the course of US history. That's the argument in historian Frederick Jackson Turner's 1893 essay, "The Significance of the Frontier in American History". Anthologized and reprinted many times, it gave historians a new lens with which to analyze the United States.

After World War II ended in 1945, the Soviet Union and the United States began a decades-long confrontation that would become known as the Cold War. American foreign policy focused on "containment" - preventing the communist USSR from gaining more ground - and many people looked at the geographical and political implications of this policy. Others, meanwhile, explored American domestic life in that same period. But historian Elaine Tyler May became the first person to bring these seemingly unrelated areas together.
