Thurgood big test occurred when the Lincoln University faculty wanted to be integrated. Thurgood voted with the majority upperclassmen to keep the faculty all white. Eventually, his classmates wanted to change Thurgood's mind when the school voted again. This time a lot of prominent upperclassmen approached Thurgoood among them were; Cab Calloway who became a famous cabaret dancer, Langston Hughes The famous poet and writer, U Simpson Tate, who later worked with Thurgood on civil rights cases, and Nnamdi Azikiwe who became president of Nigeria. Thurgood was still undecided about what to do. Thurgood remembers the days his mother and father would talk to him about how Afro Americans must stay united and stamp out segregation in any way possible. Thurgood was still undecided, so he went to his favorite professor sociologist Robert M. Labaree. Labaree told Thurgood fighting segregation is a must and the faculty should be integrated. When the decision on the integration of the faculty came up this time, Thurgood voted for the integration, and two years later the faculty was integrated. By 1930 Thurgood had graduated and received a degree in Humanities from Lincoln University. Thurgood wanted to continue his education, by enrolling at Howard University Law School located in Washington D.C. Howard Law School was the country's first black law school. Thurgood knew the law school was close to his parents home, and he could commute back and forth on the train. The man that was in charge of the all black law school was Charles Huston. Charles Huston was a true believer that Afro Americans can win the battles of segregation in the courts, instead of using physical force. Thurgood first year in law school was demanding, Charles Huston was always drilling and testing him on every aspect of the United States Constitution. Huston on countless occasions will tell Thurgood, "that you can't just understand The United States Constitution you must know how to use it and when to use it".
