How the Other Half Lives: Studies Among the Tenements of New York

In 1880s New York, half the city's population lived in darkness. Jacob Riis carried a magnesium flash into tenement apartments and photographed what the wealthy pretended did not exist: families crowded into windowless rooms, children sleeping in alleys, the dead literally stacked in backyard graves. How the Other Half Lives was journalism as revelation, a portfolio of 45 photographs and accompanying text that forced New York's elite to see the human cost of their city's growth. Riis had been a slum dweller himself, and he wrote not as an outsider but as someone who remembered the hunger. The book sparked housing reform, influenced a generation of journalists known as muckrakers, and established photojournalism as a force for social change. It remains a testament to what the camera can expose when someone refuses to look away.
