[3] Francois-Xavier rented a studio in Montparnasse, next door to friend Constantin Brâncuși, after completing mandatory military service.
Brâncuși introduced Lalanne to artists such as Max Ernst, Man Ray, Marcel Duchamp, and Jean Tinguely.
Claude Lalanne became known to the larger public in France in 1976 when the singer Serge Gainsbourg selected one of her works, "The man with the head of a cabbage", for the title and cover of an album of his.
[9][10] Les Lalanne are represented by the Paul Kasmin Gallery in New York City and Ben Brown Fine Arts in London.
Their first exhibition together included Francois-Xavier's famous rhinoceros desk, Rhinocrétaire, and Claude's cabbage with chicken legs sculpture.
