Alexander Crummell, clergyman and author, was born in New York City to free parents. Crummell was a descendant of West African royalty since his paternal grandfather was a tribal king. He attended Mulberry Street School in New York, and in 1831 he was enrolled briefly in a new high school in Canaan, New Hampshire, before it was destroyed by neighborhood residents. In 1836 Crummell attended Oneida Institute manual labor school. He was received as a candidate for Holy Orders in 1839 and applied for admission to the General Theological Seminary of the Episcopal Church, but was not admitted because of his color. He was eventually received in the diocese of Massachusetts and ordained to the diaconate there. After study at Queen's College, Cambridge, England, he went to Africa as a missionary, becoming a professor of mental and moral science in Liberia.
