Mary (Shadd) Cary was a part of the Civil Rights Movement.
Mary Ann Shadd, the first African American woman publisher in North America and the first woman publisher in Canada, was born free in Wilmington, Delaware on October 9, 1823, to Abraham Doras Shadd and Harriet Burton Parnell.
Abraham, her father, was a grandson of Hans Schad, also known as John Shadd, a native of Hesse-Cassel, who had entered the United States by serving as a Hessian soldier with the British Army during the French and Indian War. Abraham was a black agent in the Wilmington underground, and Mary grew up in a home that often hosted fugitive slaves. When it became illegal to educate African American children in the state of Delaware, the Shadd family moved to Chester County, Pennsylvania, where Mary attended a Quaker boarding school, which had a profound influence on her.
In 1840, after being away at school, Mary Ann returned to Chester and established a school for black children. She also later taught in Norristown, Pennsylvania, and New York City. The Quaker-educated teacher then moved to Canada where as a writer and editor she advocated permanent emigration from the States. Just before the Civil War she returned to the States to continue working for freedom where she was needed most.
Mary Ann was the first born of thirteen children. In 1850 her parents' household was counted on the census in West Chester, Chester County, Pennsylvania, without her. This record shows that they had lived in Delaware until after 1832 and had moved to Pennsylvania before 1836.
The move was only 17 miles away. Three years after the passage of the Fugitive Slave Act of 1850 threatened the freedom of all black Americans, A. D. Shadd moved his family to Canada West, settling in North Buxton, Ontario.
Mary Ann and her brother Isaac had already moved to Canada, immediately after passage of the act, settling in Windsor, Ontario, across the border from Detroit, where Mary Ann's efforts to create free black settlements in Canada first began. There, in 1853, Mary Ann Shadd founded a weekly anti-slavery paper, called The Provincial Freeman. She traveled throughout the U.S. and Canada at great personal risk to promote this vehicle for black self-empowerment.
She married Thomas F. Carey, a Toronto barber who was also involved with The Provincial Freeman, in Toronto, York County, Ontario, Canada in 1856.
Thomas F. Cary died just four years after they were married, while she was pregnant with their second child, Linton. 
After her husband died in 1860 in Canada, she and her children returned to the United States. During the Civil War, at the behest of the abolitionist Martin Delany, she served as a recruiting officer to enlist black volunteers for the Union Army in the state of Indiana.
After the Civil War, she taught in black schools in Wilmington, before moving to Washington, D.C.
where she taught in public schools and attended Howard University School of Law.
She attained her law degree at the age of 60 in 1883, becoming only the second black woman in the United States to do so. She wrote for the newspapers The National Era and The People's Advocate and in 1880, organized the Colored Women's Progressive Franchise.
Mary Ann Shadd Cary died on 5 June 1893 and was laid to rest in the Columbian Harmony Cemetery.
Her grave was later moved to National Harmony Memorial Park Cemetery, Hyattsville, Prince George's County, Maryland.
Mary Ann Shadd Cary's former residence in the U Street Corridor was declared a National Historic Landmark in 1976.
In 1987 she was designated a Women's History Month Honoree by the National Women's History Project.
Canada designated her a Person of National Historic Significance.
