His piece "How the Other Half Lives" showed the awful living conditions for poor people living in New York. His writing specifically focused on how this affected children." A quote that describes these conditions is "The real foundlings, the children of the gutter that are picked up by the police, are the city's wards. In midwinter, when the poor shiver in their homes, and in the dog-days when the fierce heat and foul air of the tenements smother their babies by thousands, they are found, sometimes three and four in a night, in hallways, in areas and on the doorsteps of the rich, with whose comfort in luxurious homes the wretched mother somehow connects her own misery."
