I liked your list of women. On a side note, did you know kevlar was discovered by Stephanie Kwolek? Night flares were created by a woman, then the US Navy tried to beat her to the patent office.There are so many women throughout history that have changed the world that it is hard to pick just one. Aside from great women inventors (did you know that a woman invented windshield wipers?) there were great leaders like Harriet Tubman, Mother Theresa, and Indira Ghandi.
