Added 7.18.18. Urban sociology was born in Chicago at the University of Chicago in the 1930s by street-savvy scholars who got out, explored communities and dug into non-academic realities to develop and test their theories. Broadly speaking, they were seeking  to better understand and document how immigrants, politicians, classes and interest groups in major cities relate to each other and conduct necessary social transactions, so that the urban organism is able to thrive and develop. Milt digs into the roots and present-day lessons of urban sociology for Chicago with two eminent scholars. One is Robert Sampson of Harvard University, author of “Great American City: Chicago And The Enduring Neighborhood Effect.” The other is Philip Nyden, Director of Loyola University’s Center For Urban Research and Learning. Callers add their own insights and observations, including some quite salient intel from a Chicago policeman on escalating gang-related murders.
