The Portrayed

Chief Justice Earl Warren
Chief Justice Earl Warren, who was born in 1891, secured a unanimous decision in Brown v. Board of Education, outlawing segregation in public schools and striking down the "separate but equal" doctrine of Plessy v. Ferguson. Warren also delivered the opinion in the District of Columbia case, Bolling v. Sharpe. Justice Warren died in 1974.
Thurgood Marshall
Born in 1908, Thurgood Marshall served as lead attorney for the plaintiffs in Briggs v. Elliott. From 1930 to 1933, Marshall attended Howard University Law School and came under the immediate influence of the school's new dean, Charles Hamilton Houston. Marshall, who also served as lead counsel in the Brown v. Board of Education case, went on to become the first African-American Supreme Court Justice in U.S. history. Justice Marshall died in 1993.
Judge Walter Huxman
Walter Augustus Huxman (February 16, 1887 - June 25, 1972) was an American attorney, politician, and jurist who served as the 27th governor of Kansas and a United States circuit judge of the United States Court of Appeals for the Tenth Circuit.

Huxman was a member of the three-judge federal trial court in Brown v. Board of Education, and authored the court's opinion. Despite his personal objections to the ruling in Plessy, he abided by that precedent, based on the premise that the right to overrule the Supreme Court is reserved to the Supreme Court itself.[3]
