NYC museum retrospective of photojournalist Jacob Riis

NEW YORK (AP) — A New York exhibition looks at the career of photojournalist Jacob Riis whose images of New York City's slum conditions more than 100 years ago helped spur social reforms.

"Jacob A. Riis: Revealing New York's Other Half" opens Wednesday at The Museum of the City of New York.

Riis' photographs and writings depicting the inhumane conditions of New York's immigrant poor earned him praise as the city's "most useful citizen."

The exhibition presents his photographs in various formats including lantern slides as his contemporary audience would have seen them.

It also includes Riis' papers from the Library of Congress and the New York Public Library, including scrapbooks, journals and personal correspondence.

Riis died in 1914.

The exhibition runs through March 20, 2016.
