It would be good not to forget Bayard Rustin either.
"Rustin was also a pioneer in the movement to desegregate interstate bus travel. In 1942, he boarded a bus in Louisville, bound for Nashville, and sat in the second row. A number of drivers asked him to move to the back, according to Southern practice of Jim Crow, but Rustin refused. The bus was stopped by police 13 miles north of Nashville and Rustin was arrested. He was beaten and taken to the police station, but was released uncharged"
