The Supreme Court’s 1954 Brown v. Board of Education case outlawed segregated schools. It took some time for America’s classrooms to be integrated in any significant way, especially in the Deep South. To speed up the process of achieving racial balance, beginning in the 1970s in many cities white children were bused to black schools and black children were bused to white schools. But In June 2007, the U.S. Supreme Court struck down school desegregation plans that look at students’ race. This week on the podcast, we’re featuring our 2007 documentary, “An Imperfect Revolution: Voices from the Desegregation Era,” produced by Catherine Winter and Kate Ellis.
