context: In 1910, over 2 million children in the same age group were employed in the United States. This included children who rolled cigarettes, engaged in factory work, worked as bobbin doffers in textile mills, worked in coal mines and were employed in canneries. Lewis Hine's photographs of child labourers in the 1910s powerfully evoked the plight of working children in the American south. Hines took these photographs between 1908 and 1917 as the staff photographer for the National Child Labor Committee.
