WHEN WAS IT INVENTED AND BY WHOM?
A slave called Harriet Tubman escaped from the harsh slavery she grew up doing. With all the money she had earned throughout her life she purchased a small home in Auburn, New York that was good enough to live in, and better then her life as a slave. As soon as she was free she started her mission to free slaves from the hands of their owners. She went on 15 trips Southwards to lead the Blacks to freedom. She did this by organising the Underground Railway in the North and Canada with homes along the railway that were stations for the slaves to stop at. Harriet Tubman's house was one of the stations, along with Amy Post, Isaac Post and Fredrick Douglass.
