Lewis Hine is one of the forgotten pioneers of photojournalism. Hine was a sociologist and photographer who envisioned using his photographs as instruments of social reform. The Wisconsin-born educator moved to New York City and became an educator.
His exposure to children and immigrants sparked an interest in the conditions they lived in at the time. Hine frequently took his classes to Ellis Island, where he took thousands of photos of immigrants arriving at the Statue of Liberty.
