Paul Laurence Dunbar High School was established in 1870 as the Preparatory High School for Colored Youth with 45 students and one teacher, Emma J.

This site and name remain with the school until the present day.

Before 1900, most graduates went on to study at Miner Teachers College and become teachers, but from the beginning and increasingly after 1900 it was common for graduates to attend Howard University, which taught medicine, law, and theology, or elite Northern universities such as Dartmouth (New
