The Progressive Era marks a time in American history when popular conceptions of childhood were in transition. As the Digital Public Library of America (DPLA) explains, many Progressive Era reformers, including those who protested child labor laws and sought to institute education reforms, "sought to define what a happy and healthy childhood should be in the modern age." With this DPLA exhibition, visitors can learn more about the experiences and perceptions of childhood around the turn of the twentieth century. Visitors can browse historical photographs and other images via a number of categories, including Working (featuring photographs of children laboring in factories, fields, and farms); Reform (featuring a photograph of a "Newsboys Camp" in Staten Island, one of a number of camps designed to get working children out of the city and into nature); and Children's Organizations (including photographs of Boy Scouts and Girl Scouts throughout the first half of the twentieth century). Materials in this collection are accompanied by captions that provide additional historical context and information.
