Harriet
Harriet Tubman became legendary in her lifetime as “Moses” who led so many of her people out of slavery to freedom. She was the leading “conductor” on the Underground Railroad escape route that ran in the 1850s.
Many risked their lives guiding or sheltering escaped slaves, but Tubman, who had escaped herself in 1849, went further — personally returning to Maryland to lead escape parties. She personally took at least 70 slaves out and gave instructions that allowed another 50 to escape.
