Heinrich Barth (16 February 1821  25 November 1865) was a German explorer of Africa and scholar. Barth is thought to be one of the greatest of the European explorers of Africa, as his scholarly preparation, ability to speak and write Arabic, learning African languages, and character meant that he carefully documented the details of the cultures he visited. He was among the first to comprehend the uses of oral history of peoples, and collected many. He established friendships with African rulers and scholars during his five years of travel (18501855).
