Final answer:
Dr. George R. Carruthers's immediate career move post-degree is not documented in the provided references. Booker T. Washington, however, became leader of the Tuskegee Institute.
Step-by-step explanation:
Dr. George R. Carruthers does not appear to have joined an institution in Washington immediately after getting his degree, based on the reference provided. Instead, a significant event in educational history was the hiring of Booker T. Washington at the age of twenty-five to build and lead the Tuskegee Normal and Industrial Institute (now Tuskegee University) in Alabama.
This is related more to history and the progression of African American education and leadership.
