Nabrit join hands outside the U.S. Supreme Court in Washington, D.C., after justices declared in the Brown v. Board of Education decision that separate but equal schools for black children were unconstitutional. Three years after that ruling, President Dwight D. Eisenhower dispatched federal troops to Little Rock, Ark., to escort nine black children as they integrated Central High School. The 60th anniversary of the Little Rock Nine’s enrollment is Monday, Sept. 25, 2017. (AP Photo/File)
