Discuss fundamental assumption of administrative reformers in the late 1800’s and early 1900’s.

A fundamental assumption of administrative reformers in the late 1800’s and early 1900’s was that politics could have only adverse affects on administration. How valid is that belief? Why? How, and to what extent, do current administrative structures and practices reflect that assumption? Also discuss the contributions of various scholars (at least five but preferably more) to the development of public administration as a discipline.
