Book excerpt: Leadership in American Academic Geography: The Twentieth Century examines the practice of leadership in the most influential geography departments in the United States. Throughout the twentieth century, transformational leaders often emerged as inspirational department chairs, shaping the content and nature of the discipline and establishing models of leadership, often fueling the success of programs and sparking shifts in paradigms. Yet, on occasion, departmental chairmanships fell to individuals marked by laissez faire attributes, lapses in integrity, or autocratic behaviors, which at times led to disaster. Effective leaders within key academic departments played imperative roles in the discipline’s prosperity, and in contrast, mediocrity in leadership contributed to periods of austerity. Michael S. DeVivo aims to offer not only a historical perspective on the geographic discipline, but also insight to leaders in geography, today and in the future, so that they might be able to avoid failure and instead develop strategies for success by recognizing effective leadership behaviors that foster high levels of achievement.
