Peter Hartwig (–1815) was a German-born missionary for the Anglican Church in Sierra Leone.[1] In 1803, at the age of 25, he was recruited by the Church Missionary Society to serve as one of its first two missionaries in Africa.[2] After studying English and Susu in Clapham, London, he returned to Germany and was ordained as a Lutheran in 1804. From 1804 to 1807, he served as a missionary in Freetown, but was dismissed by the CMS due to his alleged ties with slave traders. He remained in Sierra Leone for seven more years and asked to return to the mission in 1814, when he was employed as a linguist. Hartwig died in 1815 of yellow fever.[3]
