Mary Ann Shadd Cary
She was the first woman to become a publisher in Canada. Born in 1823 in Wilmington, Delaware, she escaped slavery to Canada and began teaching children of former slaves who joined her there.
The newspaper she later started called The Provincial Freemen became a weekly publication for African Americans, especially escaped slaves. She also established a school that was open to children of all races but later returned to the U.S. when the Civil War broke out to assist in the war effort.
