This book examines the transformative impact of Dorothea Lange's portraiture on our understanding of identity and inequality. Lange, a pioneering photographer, sought to capture the essence of people through her lens, revealing societal issues and shared humanity. The book delves into Lange's early work with Indigenous communities and highlights her documentation of marginalized groups such as migrant workers, striking laborers, and Japanese Americans during WWII. Drawing on fresh research, it explores her role in shaping the documentary genre. The publication, part of the National Gallery of Art's exhibition, underscores the enduring relevance of her work in contemporary discourse.
