Warren Gamaliel Bennis, Robert Townsend

 Warren Gamaliel Bennis (born March 8, 1925) is an American scholar, organizational consultant and author, widely regarded as a pioneer of the contemporary field of Leadership studies. Bennis is University Professor and Distinguished Professor of Business Administration and Founding Chairman of The Leadership Institute at the University of Southern California.

Management expert James O'Toole, in a 2005 issue of Compass, published by Harvard University's John F. Kennedy School of Government, claimed that Bennis developed "an interest in a then-nonexistent field that he would ultimately make his own -- leadership -- with the publication of his 'Revisionist Theory of Leadership' in Harvard Business Review in 1961." O'Toole observed that Bennis challenged the prevailing wisdom by showing that humanistic, democratic-style leaders are better suited to dealing with the complexity and change that characterize the leadership environment.
