Jacobus Capitein and Adoption
Capitein was a former slave brought to the Netherlands by a Dutch ship captain. In Leiden he attended school, learned several European languages and in 1742 he became a clergyman after theological school at the University there. He is probably best remembered as the author of a book defending slavery as a road to Christian redemption and European civilization. He went to the Gold Coast (Ghana) on a mission, but it was a disaster.
