Joseph Paul Gustave Vanneyre grew up in the shadow of the Abbaye d’Aiguebelle. His father was an accountant at the chocolate factory run by the monks. Married in 1929 in Le Vésinet (Yvelines), he joined the French Army, where he remained for nearly twenty years as a radiologist. It was in 1950, upon retiring, that he began an artistic career. Becoming a member of the National Union of Graphic Artists, he adopted the pseudonym Charles Lanert and painted very small oil works on pieces of wood and canvas until the 1960s, after which he preferred working in ink on paper. He then experimented, over a long period, with cutting and collage. With limited means, he salvaged whatever he could—papers, cardboard, magazine covers—and invented his own working economy. Over thirty-five years, he produced a body of work comprising several thousand pieces, in which spirituality plays a major role. One can perceive the strong influence his work as a radiologist had on him. Having become blind around 1985, Charles Lanert ceased his artistic activity and moved to Marseille.
