Between Plessy and Brown

All of these cases, as well as the upcoming Brown case, were litigated by the National Association for the Advancement of Colored People. It was Charles Hamilton Houston, a Harvard Law School graduate and law professor at Howard University, who in the 1930s first began to challenge racial discrimination in the federal courts. Thurgood Marshall, a former student of Houston's and the future Solicitor General and Associate Justice of the Supreme Court, joined him. Both men were extraordinarily skilled appellate advocates, but part of their shrewdness lay in their careful choice of which cases to litigate, selecting the best legal proving grounds for their cause.
