With the expansion of public administration as a discipline in India, the need for literature on administrative theory is being increasingly felt. This book fills the gap and covers the contributions of twenty three thinkers to the discipline. Each chapter covers an outline of the thinker’s life and work, principal contribution and a critical evaluation. This is weaved together with the contributions of twenty one professors with experience in the study, teaching and research in public administration, political science, sociology and management. It offers a single source of reference on administrative theory. Over years the book gained recognition among the students, scholars and teachers and an important source book for those appearing for competitive examinations at state and national levels.
