An anonymous reader writes: Harriet Tubman will become the first African-American woman to be featured on the face of U.S. paper currency in more than a century. Tubman was born a slave and went on to become an anti-slavery crusader. Ironically, she will be replacing Andrew Jackson, the seventh President of the U.S. and a slave owner. According to Wikipedia, "Jackson held as many as 44 [slaves] by 1820, and later held up to 150 slaves, making him among planter elite. Throughout his lifetime Jackson may have owned as many as 300 slaves." The decision to feature a woman on a bill started in part from a young girl's letter to President Obama about the lack of women on U.S. currency. A social media campaign "Women on 20s" then began pushing for a woman to replace Jackson on the currency early last year. Originally, the department announced it would feature a woman on the $10 bill instead of Alexander Hamilton. Now it's being reported Hamilton will stay on the front of the bill with a group of women on the back of it. Civil rights era leaders will reportedly be depicted in the new $5 bill.
