I would thank Harriet Tubman for freeing the thousands of slaves she led to freedom. I would thank her for being brave enough to not only look after herself but all the other slaves who had a chance at freedom because of her.
It would have to be Mae Carol Jemison, she was an American engineer, physician, and former NASA astronaut. She was the first black woman to travel into space when she served as a mission specialist aboard the Space Shuttle Endeavour. Her time in space was 7days 22hours 30minutes. If I could ask her anything I would ask her if she knew she wouldn't be the last African American woman to travel to space.
