Born in 1840, Henry Johnson was the son of Christian converts in Sierra Leone. In 1865 he went to England to train for the ministry and in 1866 he was ordained a deacon in London. The following year he was made a priest by the Bishop of London. He worked in England for two years before returning to Sierra Leone to work on translations. A prolific translator, he translated most of the New Testament books into the Mende language. He eventually became the Archdeacon of the Upper Niger and on 12 November 1885 was awarded an honorary M.A. by the University of Cambridge.
