What was Arthur Wergs Mitchell’s relationship with Booker T. Washington?

Arthur Wergs Mitchell briefly attended the Tuskegee Normal and Industrial Institute, a vocational school for African Americans that was founded by Booker T. Washington in Tuskegee, Alabama. As a student, Mitchell worked as an assistant in Washington’s office, and he adopted Washington’s views on race relations, which favored pragmatism and accommodation instead of political protest. However, controversies regarding another vocational school for African Americans that Mitchell founded led Washington to caution investors against donating to Mitchell’s school, and Mitchell responded by attempting to blackmail his former mentor.
