Florence Barbara Maria von Sass (August 6, 1841 - March 11, 1916) was a Hungarian-born British explorer. Orphaned during the Hungarian Revolution of 1848, she was sent to an Ottoman harem, where she lived as a chore girl until she hit puberty, when she was sold to a slave auction. Samuel Baker (June 8, 1821 - December 30, 1893) an English explorer, and big game hunter, became entranced by the teenager on the slave block. When he couldn’t outbid the pasha, he bribed the guards and Florence was allowed to escape with him. They set off to Africa in 1861, first exploring Ethiopia, then setting their sights on discovering the source of the River Nile. In 1869 they returned to Gondokoro as abolitionists.
