Hailing from Wilmington, Del., Mary Ann Shadd made history in 1853 as the first Black woman to hold the title of “publisher.” According to Britannica Encyclopedia, Shadd began encouraging Black people in America to make a run for Canada by publishing the success stories of free Black people in her new country. Shadd would go on to serve as a school teacher and a recruiter for Union forces during the American Civil War. (Photo Courtesy of Britannica Encyclopedia)
