Book excerpt: One of America’s leading curators, “a woman of resilience and vision, a writer of clarity and ardor” (Chicago Tribune), takes you on a personal tour of the world of modern art. In the Depression-era climate of the 1930s, Katharine Kuh defied the odds and opened a gallery in Chicago, where she exhibited such relatively unknown artists as Fernand Léger, Paul Klee, Joan Miró, Ansel Adams, Marc Chagall, and Alexander Calder. Her extraordinary story reveals how and why America became a major force in the world of contemporary art.
