Thurgood Marshall was born in 1908 in Baltimore, Maryland. His father was a railroad porter and steward and his mother a teacher. After graduating from Lincoln University, he was rejected from the all-white University of Maryland Law School, he attended Howard University Law School. He graduated at the top of his class in 1933, he went into private practice and worked on different civil rights suits. One successful suit was against the University of Maryland Law SchooL for denying a Black applicant solely based on race.

Marshall worked for the NAACP first as a staff lawyer, then as a lead chair, and a few years later as the chief of the Legal Defense and Education Fund. He won 29 of the 32 cases the NAACP brought before the U.S. Supreme Court, which related to voting rights issues, segregation and more. His most famous case was Brown v. Board of Education of Topeka in which "separate but equal" as a justification for segregation was struck down. Marshall was later named U.S. solicitor general and nominated to the U.S. Supreme Court. Here he continued to advocate for change and justice for marginalized peoples throughout the United States. He retired with the nickname "the Great Dissenter," indicative of his continued commitment to advocacy even in the midst of a conservative court.
