Washington is far from the greatest mind on this list. Others impacted world history, science, medicine, or theology more- but Washington is a difficult figure in history to truly know and comprehend. He was painfully aware that didn't posses a mind of Adams or Jefferson. He was meticulous in his personal affairs- (Washington, unlike other famous Virginia planters, didn't owe money to British creditors) He didn't attend University to absorb all the secular Age of Reason and Enlightenment philosophy that laid the groundwork for the revolution. And he didn't leave piles of letters for posterity and legend-building unlike other Founding Fathers (who knew that their writings would be analyzed.) But unlike a Caesar or a tyrant, he simply left power and allowed for an election. (Yes, age had much to do with it but find me anyone who left such power voluntarily) Washington might be the most underrated interview on this list if you really think about it.
