James Nabrit Jr came to the District as an up-and-coming Howard law professor. He developed the first course at an American law school on civil rights law and instilled in his students an unrelenting belief in the immorality and impracticality of the Plessy v. Ferguson decision. As the lead counsel for the District's Bolling v. Sharpe case, Nabrit championed the position of attacking segregation outright, instead of relying on equalization. He pushed Thurgood Marshall and the NAACP to sharpen their attacks on school segregation and strongly influenced the outcome of all of the Brown v. Board school cases.
