Details:
Jacob Riis was a police reporter in New York. Â In 1888, Riis took pictures of what life was like in city's slums. Â Using his own photos as well as photos gathered from other photographers, Riis began to give lectures titled, "The Other Half: How It Lives and Dies in New York," in which he would show the pictures on a projection screen and describe for viewers what the situations were like. Â He gave his lectures in New York City churches. Â In 1989, a magazine article by Riis (based on his lectures) was published in Scribner's Magazine. Â The book version was then published in 1890 as How the Other Half Lives: Studies among the Tenements of New York.
Riis blamed the poor living conditions on greed and neglect from society's wealthier classes, and called on society to remedy the situation as a moral obligation.
