From the text of the story from KQED: 

     A month ago, you may have read about an organization called Women On 20s, whose mission is to put a woman’s face on paper currency by 2020. More than 256,000 followers of the campaign voted to narrow the nominees down from 100 to four. They settled on Rosa Parks, Harriet Tubman, Eleanor Roosevelt, and Wilma Mankiller.
     After another voting round, Harriet Tubman has emerged as the nominee that will be used to convince the Treasury Department to make history by better representing history.
     For those who didn’t pay attention in school or are from Mars, Tubman was considered the “Moses” of her time. Born into slavery, she managed to escape to the North and then proceeded to return to the South (19 TIMES!) to lead 300 others—including her siblings and parents—to freedom, using her knowledge of safe-houses.
