Blanche Bruce
Blanche Kelso Bruce was a U.S. politician who represented Mississippi as a Republican in the U.S. Senate from 1875 to 1881 of mixed race, he was the first elected black senator to serve a full term. Hiram R. Revels, also of Mississippi, was the first African American to serve in the U.S. Senate, but did not serve a full term.
Bruce was born into slavery in 1841 in Prince Edward County, Virginia near Farmville to Polly Bruce, an enslaved AfricanAmerican woman who served as a domestic slave. His father was her master, Pettis Perkinson, a white Virginia planter. Bruce was treated comparatively well by his father, who educated him together with a legitimate halfbrother. When Blanche Bruce was young, he played with his halfbrother. His father legally freed Blanche and arranged for an apprenticeship so he could learn a trade.
