What contribution was made by the Chicago school and why Chicago?

Answer:
Hey dork, if you're going to ask people to do your homework, you should at least be bright enough to know that multiple topical areas have a "Chicago School," the three biggest being architecture, economics and sociology, but there are others.

If you want an answer, at least ask the right question.
