Lewis Hine definitely has a long and complicated history. When Hine had to take charge of the household after his father died, he found himself working in a factory with long hours. Eventually, Hine decided to go to college. After that, he became a teacher and photographer for a school through a connection with Frank Manny. As Hine's photography became more and more sough after. Hine's works were published in several magazines, but then he decided to document the unsafe working conditions for children in factories. In order to do this, he would sneak his way in and take pictures of the kids working. This was dangerous for him because the owners of the factory were often threatening to anyone who had anything to do with the child labor reforms. These pictures aided in changes of child labor laws, so Hine really made an impact. Hine is also famous for risking his life taking pictures of men risking their lives building. These photos were eventually titled "Men at Work." In final consideration, Hine was not afraid about how his pictures would impact his life; he only seemed to care about the well-beings of others.
