Here is access to a podcast interview with Oliver Hill, a civil rights attorney who was part of the NAACP 50’s/60’s legal push for civil rights, equality, and modernity.
"Civil rights attorney Oliver Hill is well known for the role he played in the landmark U.S. Supreme Court decisions that ended the doctrine of “separate but equal” and other forms of racial discrimination in the United States. One of the cases in which Hill was a key figure was NAACP v. Button. On its face, Button was a challenge to Virginia statutes defining and punishing attorney malpractice. The impact of the 1963 decision was, however, far greater. NAACP v. Button established the principle that active encouragement of public interest litigation is “speech” protected by the First Amendment – a principle that was critical to civil rights litigation."
