Oppenheimer was not oblivious to these issues. Indeed, early that autumn of 1922 he joined the Student Liberal Club, founded three years earlier as a forum for students to discuss politics and current events. In its early years, the club attracted large audiences with such speakers as the liberal journalist Lincoln Steffens, Samuel Gompers of the American Federation of Labor and the pacifist A. J. Muste. In March 1923, the club took a formal stand against the university’s discriminatory admissions policies.
