Edgar Stuart, Duke of Cambridge (14 September 1667 – 8 June 1671) was the fourth son of James, Duke of York (later James II of England) and his first wife Anne Hyde. He was second in the line of succession to the English and Scottish thrones.
Pierre Paul François Camille Savorgnan de Brazza (born Pietro Paolo Savorgnan di Brazzà; 26 January 1852 – 14 September 1905) was an Italian-French explorer. With his family's financial help, he explored the Ogooué region of Central Africa, and later with the backing of the Société de Géographie de Paris, he reached far into the interior along the right bank of the Congo River. He has often been depicted as a man of friendly manner, great charm and peaceful approach towards the Africans he met and worked with on his journeys, but recent research has revealed that he in fact alternated this kind of approach with more calculated deceit and at times relentless armed violence towards local populations. Under French colonial rule, the capital of the Republic of the Congo was named Brazzaville after him and the name was retained by the post-colonial rulers, one of the few African nations to do so. (Other exceptions are Pretoria, South Africa, Port Louis, Mauritius, Libreville ,Gabon, and Victoria, Seychelles.)
