Born in Paris in 1935, Jean-Pierre Cassigneul studied and graduated from the École Nationale Supérieure des Beaux-Arts, having held his first one-man show at the age of 17.
From 1956 until 1960 Roger Chapelain-Midy instructed Cassigneul. During this period, he held exhibitions in Paris and other cities. He had a contract with the Galerie Bellechasse in Paris for several years after his first exhibition there in 1965. Since then, his work has been exhibited extensively throughout Europe, Japan and the United States, including shows at the Galerie Tivey Faucon in Paris, Galerie Tamenaga in Japan and Wally Findlay Gallery in New York. Cassigneul has also illustrated several books, including Le Tour de Malheur by Joseph Kessel. Cassigneul creates beautiful compositions of striking young women very much in the tradition of the early 20th century French Nabis artists, like Pierre Bonnard and Edouard Vuillard. A great influence very much apparent in his work is that of the expressionist painter Kees van Dongen, especially Cassigneul’s very dramatic portraits and his use of intense vibrant color.
