Answer: Thurgood Marshall.
Explanation:
Thurgood Marshall (1908-1993) was a key element in ceasing legal segregation. His work in NAACP led the judiciary to support equality for African Americans. In the Brown v. Board of Education case (1954) he got the Supreme Court to stop racial segregation in public schools. In 1967 he was selected as an associate justice of the Supreme Court, becoming the first African-American to do so.
