Jacob Riis is regarded as a pioneer of photography because he demonstrated that photographs could be powerful tools for social reform. His images of poverty in late nineteenth-century New York exposed living conditions that were largely hidden from the middle and upper classes, helping to establish documentary photography as a force for public awareness and political change.
His pioneering contributions include:
Pioneering social documentary photography: Riis photographed overcrowded tenements, child labourers, homeless people and immigrant communities, using photography to reveal the realities of urban poverty rather than simply recording events.
Innovative use of flash photography: At a time when photography required long exposures and abundant daylight, Riis was among the first to use magnesium flash powder to photograph dark interiors, cellars and alleyways. This made it possible to document places that had previously been inaccessible to photographers.
Photography as an instrument of reform: Riis believed photographs could influence public opinion more effectively than words alone. His images were used to advocate for better housing, sanitation and public health, demonstrating photography’s potential to inspire social change.
Combining photographs with investigative journalism: As a journalist, Riis integrated photographs with detailed reporting. This combination of visual evidence and written testimony became a model for later documentary photographers and photojournalists.
Publication of How the Other Half Lives: How the Other Half Lives brought his photographs and observations to a wide audience. The book shocked readers and played a significant role in campaigns for housing reform and improved urban conditions.
Influencing public policy: Riis’s work attracted the attention of politicians and reformers, including Theodore Roosevelt, who worked with him when serving as New York City’s Police Commissioner. Their efforts contributed to reforms in policing, housing and public welfare.
Establishing ethical documentary traditions: Although some aspects of his methods and attitudes are criticised today—particularly his occasional staging of scenes and the cultural biases reflected in some of his writings—his work established the principle that photography could document social issues and encourage reform.
Influencing later documentary photographers: Riis’s example inspired photographers such as Lewis Hine, the photographers of the Farm Security Administration, and many modern photojournalists who use photography to examine social injustice.
Lasting legacy
Jacob Riis’s greatest contribution was proving that photography could do more than create art or preserve memories—it could expose injustice and influence society. By combining photographic innovation with investigative reporting and reform activism, he helped lay the foundations of modern documentary photography and photojournalism. While his work is now viewed through a more critical historical lens, particularly regarding issues of representation and bias, his role in establishing photography as a catalyst for social awareness and change remains highly significant.
