Abolitionist and activist Harriet Tubman will potentially soon replace Andrew Jackson on the $20 bill. Born into enslavement in Maryland, Harriet Tubman escaped to freedom in Pennsylvania in 1849 to become the most famous “conductor” on the Underground Railroad, an elaborate secret network of safe houses. For more on the life of Harriet Tubman we speak with Dr. Gregory Carr (@AfricanaCarr), Associate Professor of Africana Studies and Chair of the Department of Afro-American Studies at Howard University.
