Pick a single word that comes to mind just by saying their names. All come from essentially the same generation. All had great dedication and limitless work ethics. All deserve a great amount of study. There is much for us to learn about leadership from reading about their lives.
Biographies are a limitless treasure of leadership research.
The world of biographies offers windows into the worlds and lives of our heroes. We can pick those who we imagine most to be like us. We can choose those who we would most like to be. We can choose those who have worked in our profession or those whose reputation is so abhorrent we want to be certain never to be anything like them. The only common ingredient to all these potentially enlightening experiences is the discipline necessary to do the study.
