What Jane Jacobs knew (The Atlantic)
by Nathaniel Rich
Jane Jacobs revolutionized our understanding of the lives of cities. But the scholar’s life and work—from her time living in a desperately declining small town, to her work as a propagandist during World War II—reveals broader truths about how Americans can live together.
