Born as Araminta Ross into slavery in Maryland’s Dorchester County around 1820, the woman we now know as Harriet Tubman became one of the abolitionist movement’s most famous “conductors” in the Underground Railroad. Tubman made 19 harrowing trips into the South to provide escaped slaves safe passage. She married John Tubman, a free black man, around 1844. Eventually, the South put a $40,000 price on her head for freeing slaves, quite a lot for 1856. And she didn’t hesitate to defend herself with a pistol, famously saying “dead Negroes tell no tales.” “General Tubman” also coordinated with abolitionist John Brown to conduct his raid on Harpers Ferry in 1858. During the Civil War, she served for the Union army as a cook, a nurse, and a spy. After the war, she settled in Auburn, New York. Tubman is such a popular figure that she won an online poll run by Women on 20s, which seeks to replace genocidal maniac Andrew Jackson with a woman on the $20 bill.
