Doris Kearns Goodwin’s new book, Leadership in Turbulent Times, is a culmination of five decades of studying American Presidents. Combining her signature storytelling with essential lessons from four of our nation’s presidents—Abraham Lincoln, Theodore Roosevelt, Franklin D. Roosevelt, and Lyndon B. Johnson—Goodwin explores their unique journeys to recognize themselves as leaders, the ways in which they navigated adversity, and how they emerged to confront the challenges and contours of their times.
