Florence Barbara Maria von Sass was a British explorer and abolitionist. Born in Hungary (today Romania), Florence's family was killed during the Hungarian Revolution of 1848 leaving her orphaned. When she was fourteen she was sold as a slave in Vidin to Samuel Baker a British explorer and naturalist. Baker was on a hunting trip at the time and allegedly bribed the guards for her after she was intended to be owned by the Pasha of Vidin. Florence and Baker went to Africa where Baker was on an expedition to find the source of the Nile. While traveling in Africa, Florence and Baker came across Murchison Falls and Lake Albert. In 1865 the couple married and Florence became Lady Baker when Samuel Baker was knighted. Due to her parentage and upbringing, although she was a Lady, Florence was not welcome at court. Besides exploration, the Bakers were also abolitionists and in 1869 returned to Africa to help reduce the slave trade in Gondokoro where Florence worked as a medic. Florence and her husband retired to Devon where Florence died in 1916.
