I was so glad to see your editorial on Harriet Tubman and the $20 bill ("Capitalizing on Harriet," May 20). Now, please take up your own challenge and learn more about Harriet. Just a minor correction: She was not injured by a rock but by a store weight at a store whose location you can still visit here in Dorchester County.
She was also a spy for the Union Army while working as a cook for the Union Army's Colored Troops stationed in South Carolina, was a very active women's rights activist and worked to provide care for the elderly and indigent in her home in New York State.
And while I have your attention, the City of Cambridge is hosting the 6th Annual Harriet Tubman Underground Railroad Conference where you can check out all the latest research on Harriet and the other less famous but still crucial conductors and supporters for the cause of freedom.
