Louis de Clercq (1836-1901) was a French collector born in Oignies, northern France. His collection was formed in the late 19th century, inspired by his travels to the Middle East and Mediterranean, where he was a photographer on a Ministry of Public Instruction expedition. The de Clercq collection is notable as much for its discerning quality as its rich breadth. It was published in seven volumes from 1885-1911, with the subjects as diverse as ancient Assyria, jewellery, marbles, and Cypriot art. Many notable pieces from the Department of Oriental Antiquities at the Musée du Louvre were gifted from this collection in the 1970s.
