Nine-year-old African-American student Linda Brown poses outside Sumner Elementary School in Topeka, Kan., in 1953. When her enrollment in the racially segregated school was blocked, her family initiated the landmark civil rights lawsuit <i>Brown</i> v. <i>Board of Education</i> that led to the Supreme Court decision outlawing racial segregation in U.S. schools. A new lawsuit in Massachusetts challenges persistent segregation in that state's schools.
