Mary Harris, later known as Mother Jones, was born in Ireland in 1830 and immigrated to the United States as a young woman. With prodigious energy and a gift for oratory, she became one of America's most influential union organizers. Looking frail and grandmotherly in her prim black dress, steel-rimmed glasses, and white hair, this tiny, indomitable woman gave stirring speeches urging workers to stand up for their rights, bullied government officials, and fearlessly confronted business leaders. Betsy Harvey Kraft's clear, meticulously researched text introduces an important figure in American social history to a new generation.
