The Henry Crown Fellowship Program was established in 1997 by the Aspen Institute. Henry Crown Fellows spend four weeks in structured retreat—exploring their leadership, their core values, their vision for a “Good Society” and their desired legacies. But the Fellowship is not just about reflection. It is also about action: Each Fellow launches a new initiative that will stretch them and have a positive impact on their communities, their country or the world. Each class of 20-21 are "accomplished entrepreneurial leaders (between the ages of 30 and 45)" Rank numbers represent the class year of attendance.
