Green Bay High School. Green Bay High School traces its origin to October 11, 1889, when eleven black men of the community formed a board of trustees and organized a school for the area's black children. The first school facility was provided by Green Bay Methodist Church. New school buildings erected in the early 1900s also housed the Mt. Sinai Masonic Lodge. Many dedicated teachers served in the Green Bay School, and students from a large rural area attended the school from its creation until desegration of area school systems was achieved in 1966.
