Walter Reed Army Medical Center, the Army's flagship hospital where privates to presidents have gone for care, is closing its doors after more than a century. Hundreds of thousands of the nation's war wounded from World War I to today have received treatment at Walter Reed, including 18,000 troops who served in Iraq and Afghanistan. President Dwight Eisenhower died there. So did Gens. John J. Pershing and Douglas MacArthur. It's where countless celebrities, from Bob Hope to quarterback Tom Brady, have stopped to show their respect to the wounded. Through the use of medical diplomacy, the center also has tended to foreign leaders. The storied hospital, which opened in 1909, was scarred by a 2007 scandal about substandard living conditions on its grounds for wounded troops in outpatient care and the red tape they faced. It led to improved care for the wounded, at Walter Reed and throughout the military. By then, however, plans were moving forward to close Walter Reed's campus.
