Belgian lawyer, archivist, diplomat, author and antiquary. He spent his later life in the United Kingdom, and is best known for his studies of macaronic language and literature.
Living in England, Delepierre wrote an account in 1849 of a collection of early French farces and morality plays in the British Museum. In 1852 he produced Macaronéana, followed by Macaronéana Andra in 1862. These publications formed an encyclopædia of information on macaronic literature.
Delepierre died on 18 August 1879, aged 77, at London, England.
