So, welcome Dr. Simon. Thank you. It's wonderful to talk to you about Settlement Houses. Thank you, Dr. Robert. So, when you think about Settlement Houses, you think about a variety of places with variety of names. I do. Settlement Houses were initially called that in the 1880s and 1890s, beginning in England and then here, and then it's now in- it's estimated 72 countries across the globe. The term Settlement Houses is synonymous with Community Centers and with Neighborhood Houses or Neighborhood Centers. The term initially was about reformers in the progressive period feeling that it was important to live among the people one was working with as neighbors not as outsiders coming in to provide a service, but rather as neighbors sharing a neighborhood. That's no longer the case, in that the work has been professionalized. So, how has Settlement House changed things? What difference have they made? In the United States, Settlement Houses have their workers and their leaders have initiated many of the public resources or public goods that we now take for granted like public parks, public recreation areas, the school recreational areas, community gardens, regulations regarding clean water, and inside plumbing, and ventilation in apartments, amount of space per square foot per person so their density requirements in housing that have come out of progressive era settlement housework. Settlements have had three parts from the beginning, only two of which are left, but three that prevailed for about 40 years. They are Service, Advocacy and Research. Service had to do with responding to the needs of two main groups of people. The largest group were immigrants, newly come from many parts of the world. The second group were African-Americans who migrated north after slavery was ended and during in addition to the difficulties of the Jim Crow period and when jobs, of course, opened up during World War I, when many white men went to war as did black men and, therefore, industrial jobs opened up. That cause industrialists to drop the racial segregation that had previously kept them from hiring black workers. So, it sounds like Settlement Houses have had a big effect on social welfare in the United States. I think a huge effect. Whether we look at housing, not only public housing, but also economically accessible housing. The push for accessible housing that regular people could afford has been at the heart of settlement housework since the beginning. So has the focus on environmental living conditions. Do we have areas to grow green things? Can we purchase fresh food? The whole notion of bringing in food from nearby farmers as well as raising some in a community garden was a very early settlement house push in the 19th century, which now, of course, is a big idea and a big effort on the part of many people. In addition, regulating work and workplaces, making them less dangerous, making them places where you could earn a living wage, making them places where women and people of color are not as discriminated against as they once were, making it so that children wouldn't be workers anymore prior to the age of 16 except in a family business. The fight against child labor was a big one and not a popular one at first since many immigrant families needed the wages that small children would bring in, but the Settlement House workers fought very hard to get rid of child labor at the same time that they were fighting to make public school universally available. So, thank you, Dr. Simon. It has been great to have you. Thank you, Dr. Robertson.
