Doris Kearns Goodwin (@DorisKGoodwin) is a biographer, historian, and political commentator who found her curiosity about leadership sparked more than half century ago as a professor at Harvard. Her experiences working for LBJ in the White House and later assisting him on his memoirs led to her first book, Lyndon Johnson and the American Dream. She followed up with the Pulitzer Prize-winning No Ordinary Time: Franklin and Eleanor Roosevelt: The Home Front in World War II. She earned the Lincoln Prize for the runaway bestseller Team of Rivals, the basis for Steven Spielberg's award-winning film Lincoln, and the Carnegie Medal for The Bully Pulpit, the chronicle of the friendship between Theodore Roosevelt and William Howard Taft.Her newest book, Leadership: In Turbulent Times, examines how the four presidents she's studied most closely — Lincoln, Theodore Roosevelt, FDR, and LBJ — found their footing. It goes all the way back to when they first entered public life and takes a look at the daily habits, tricks, and tools they used to navigate confusion, uncertainty, fear, and hope to establish themselves as leaders.Enjoy!This podcast is brought to you by Audible.
