Thoroughgood "Thurgood" Marshall (July 2, 1908Β β 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. Before 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 American public 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.
Born in Baltimore, Maryland, Marshall attended Lincoln University and the Howard University School of Law. At Howard, he was mentored by Charles Hamilton Houston, who taught his students to be "social engineers" willing to use the law to fight for civil rights. Marshall opened a law practice in Baltimore but soon joined Houston at the NAACP in New York. They worked together on the segregation case of Missouri ex rel. Gaines v. Canada; after Houston returned to Washington, Marshall took his place as special counsel of the NAACP, and he became director-counsel of the newly formed NAACP Legal Defense and Educational Fund. He participated in numerous landmark Supreme Court cases involving civil rights, including Smith v. Allwright, Morgan v. Virginia, Shelley v. Kraemer, McLaurin v. Oklahoma State Regents, Sweatt v. Painter, Brown, and Cooper v. Aaron. His approach to desegregation cases emphasized the use of sociological data to show that segregation was inherently unequal.
