The Handbook of Leadership Theory and Practice seeks to bridge this disconnect. Based on the Harvard Business School Centennial Colloquium “Leadership: Advancing an Intellectual Discipline†and edited by Harvard Business School professors Nitin Nohria and Rakesh Khurana, this volume brings together the most important scholars from fields as diverse as psychology, sociology, economics, and history to take stock of what we know about leadership and to set an agenda for future research.
