Book excerpt: As head of the National Consumers' League from its founding in 1899 until her death in 1932, Florence Kelley led campaigns that reshaped the conditions under which goods were produced in the United States. She also worked to pass laws providing for an eight-hour workday, a minimum wage, the first federal health legislation for women and children, and abolition of child labor. An ally of W.E.B. DuBois, she was a founding member of the National Association for the Advancement of Colored People and served on its board for twenty years. This volume collects nearly three hundred of Kelley's letters, written over the course of more than six decades. Rendered in Kelley's vivid, often combative prose, these letters also provide an intimate view into the personal life of a dedicated reformer who balanced her career with her responsibilities as a single mother of three children.
