One significant figure in Black history who became a U.S. Supreme Court justice is Thurgood Marshall. Marshall was appointed as an Associate Justice of the Supreme Court by President Lyndon B. Johnson in 1967, making him the first African American to serve on the highest court in the United States.

Before his appointment to the Supreme Court, Thurgood Marshall was a prominent civil rights attorney and a leading figure in the legal battles against segregation and discrimination. He successfully argued several cases before the Supreme Court, including the landmark case Brown v. Board of Education, which led to the desegregation of public schools.

During his tenure on the Supreme Court, Justice Marshall continued to be a champion of civil rights and social justice. He consistently advocated for the protection of individual liberties and equality under the law. Marshall served on the Court for 24 years until his retirement in 1991, leaving behind a legacy of commitment to justice and equality for all.
