Who is Ludwig von Mises from Capitalism, the Unknown Ideal and what is their importance?

Ludwig von Mises was a professor who also studied living conditions during the Industrial Revolution. He points out factory workers were paid wages better than workers could earn in other forms of employment. By offering employment to women and children, the factory provided them with a livelihood which saved many of them from starvation. The women had nothing to do in their homes and the children were not in school or playing. They were all starving. The factories saved the lives of many of them.
