The Dallas Arboretum has selected Admiral William H. McRaven, former University of Texas System chancellor and retired U.S. Navy four-star admiral, for its Great Contributors Award. He will be honored on Sunday, November 5 at a dinner with proceeds benefitting the Dallas Arboretum. After dinner, former U.S. Ambassador to NATO and U.S. Senator Kay Bailey Hutchison will interview Admiral McRaven about world affairs, intelligence and national security—topics on which both are experts.
