Lewis W. Hine utilized his camera not only to take memorable photographs but to help elicit social reform. A sociology student at New York University, Colombia University and the University of Chicago, Hine went on to become a teacher. In his classroom he often encouraged his students to use photography as an educational medium. He brought his classes to Ellis Island in New York Harbor to photograph the thousands of immigrants who arrived each day. Between the years of 1904 and 1909 Hine is said to have photographed over 200 plates and this experience made him realize that photojournalism was his true calling. Over the years his work helped with social reform bringing images of children laborers and Steel workers to light in the hopes of improving their lives.
