How the Other Half Lives Studies among the Tenements of New York by Jacob A. Rii

A photographic collection exposing social conditions and daily life in the slums of late 19th century New York City. The title of the book is a reference to a sentence by French writer and philosopher François Rabelais, who famously wrote in his Pantagruel : "one half of the world does not know how the other half lives" ("la moitié du monde ne sait pas comment l'autre vit").
