The Aesthetic Movement meets Jules Verne, with a dash of French Deco and a dollop of Surrealism. The art of Claude and François-Xavier Lalanne, married Parisians who called themselves “Les Lalanne” even though they created their sculptural pieces separately, is deeply rooted in nature’s flora and fauna. The work is art-historically knowing, yet whimsically inventive. A welded-copper rhinoceros opens into a desk. A wire treillage is shaped like a human head. A patinated bronze cabbage sports the legs of a chicken. François-Xavier died in 2008 and Claude followed in 2019. Since then, the Lalanne family has donated 54 works—16 sculptures and 38 drawings—to the French State, in lieu of death tax duties. This is a rich gift, and it’s now on view in Paris. —Laura Jacobs
