Answer:
Thurgood Marshall
Step-by-step explanation:
Thurgood Marshall represented the Brown family in the famous Supreme Court case Brown vs. Board of Education. Marshall, a lawyer for the NAACP, argued that the doctrine of "separate but equal" for public schools was a clear violation of the 14th amendment. More specifically, separate schools for black and white citizens violated the Equal Protection clause of the 14th amendment.
Marshall was successful in presenting his argument, as the Supreme Court ruled in favor of the Brown family. This resulted in the desegregation of public schools throughout the United States.
