Florence Kelley (1859 –1932) was an American social and political reformer, known for her work against sweatshops and for the minimum wage, eight-hour workdays and children's rights. 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. Du Bois, she was a founding member of the National Association for the Advancement of Colored People and served on its board for twenty years.The volume collects nearly three hundred of Florence Kelley's letters.
