One prominent U.S. judge in Black history is Thurgood Marshall. Marshall was the first African American to serve on the Supreme Court of the United States, where he served from 1967 to 1991. Before his Supreme Court appointment, Marshall was a key figure in the civil rights movement as a lawyer, most notably as the lead attorney for the NAACP Legal Defense Fund. He argued several landmark civil rights cases before the Supreme Court, including Brown v. Board of Education, which led to the end of legal segregation in public schools. Marshall's legacy as a judge and civil rights advocate has left an indelible mark on American history.
