Nineteenth century universities had departments of philosophy, they had departments of mathematics, they had departments of literature, they had departments of theology, and some of them might have had a department for physics, some sciences. But a 19th century university would not have had any social science at all. Social science is really invented in the progressive era. We create the idea of the study of how human beings develop and function in psychology. We developed the study of how we do business, how we make what we need, how we share what we need, how we build a productive world together in the study of economics. We study how we live together, how our families form, how our communities form, how we build effective organizations in sociology. We studied the bases of how our psyche was developed historically, how our culture was, how are families were in anthropology. Then, in this period of time, medicine went from being somebody that traveled with a doctor for a few years and then apprenticed with that doctor, and hung up his own shingle, and it would have been a his, and declared himself a doctor to medicine based on science. So in the 1890s and the 1900s, we created medical schools and medicine shifted from being an apprentice-based trade to an education-based trade based on science and medical licenses were required. Medical schools were formed, epidemiology was studied, the public health movement was developed. All of this was this expansion of Social Science and Social Research. As part of that, social welfare was developed and the social work schools were formed. So in 1896, none of these departments would have existed. By 1910, all of the universities in America would have had social science departments. Two really early parts of this, one I spoke about earlier was the Philadelphia study that William Dubois did in Philadelphia. Another one was a Pittsburgh survey by Paul Kellogg, who is related to the cereal company, to understand how people were living in the cities. Steady income, family structures, study poverties, study child-rearing, so that we developed a much deeper sense of who we were as a city together. This led to the formation of something called the Russel Sage Foundation which still continues as a major source of social science research. Federally, it resulted in the formation of the first White House Conference on Children, and really the federal interests in developmental interests in children. So, this development of social research became a central part of the expansion of the progressive era.
