Jacob Rill's goal in the late 1800s was  to make Americans aware of problems in cities.

Riis' goal was to expose the conditions of the poor living in the tenements and slums of New York City.  A book called How the Other Half Lives, published dramatics photos seeking to show people the deplorable conditions the city's poor were living in. These photographs also convinced people that a change was vital to happen and the poor needed to be helped.
