One significant U.S. Supreme Court Justice in Black history is Thurgood Marshall. Marshall was the first African American to serve on the Supreme Court, appointed by President Lyndon B. Johnson in 1967. Before becoming a justice, Marshall was a pioneering civil rights attorney who successfully argued several landmark cases, including Brown v. Board of Education, which led to the desegregation of public schools in the United States. As a Supreme Court Justice, Marshall continued to champion civil rights and equality, and his decisions helped advance the cause of justice for marginalized and oppressed communities. He retired from the Supreme Court in 1991 but left a lasting legacy as a trailblazer for racial equality and justice in America.
