Dutch painter and engraver. He often depicted Dutch historic scenes and figures (particularly from the Dutch Golden Age), contributing several paintings to Jacob de Vos Jacobszoon's gallery of oil paintings depicting scenes from Dutch history. Cornet also painted and drew portraits, landscapes, interiors and a range of other subjects. Cornet received instruction in drawing in Leiden but was largely self-taught. He was one of the founders of the Lakenhal museum in Leiden. He was also a director of the Leiden artists' society Ars Aemula Naturae and a member of the Amsterdam artists' society Arti et Amicitiae. He served as head of the Prentenkabinet (cabinet of prints) in Leiden from 1851 to his death in 1882. A Cornet painting dating to about 1845, now in the collection of the Lakenhal museum, depicts the 17th-century painter Paulus Potter. The Rijksmuseum in Amsterdam has an 1848 portrait by Cornet of the painter David Pierre Giottino Humbert de Superville. //
