Thurgood Marshall (July 2, 1908 – January 24, 1993) was an American civil rights lawyer and jurist who served as an associate justice of the Supreme Court of the United States from 1967 until 1991. He was the Supreme Court’s first African-American justice. Prior to his judicial service, he was an attorney who fought for civil rights, leading the NAACP Legal Defense and Educational Fund. Marshall was a prominent figure in the movement to end racial segregation in schools. He won 29 of the 32 civil rights cases he argued before the Supreme Court, culminating in the Court’s landmark 1954 decision in Brown v. Board of Education, which rejected the separate but equal doctrine and held segregation in public education to be unconstitutional. President Lyndon B. Johnson appointed Marshall to the Supreme Court in 1967. A staunch liberal, he frequently dissented as the Court became increasingly conservative.
