Annette Laming-Emperaire (22 October 1917 – May 1977) was a French archeologist.

Born in Petrograd, Annette Laming studied philosophy in Paris until World War II began. She then turned to teaching while participating in the French Resistance.^[1] After the war, she studied archeology and specialized in cave art; her doctoral thesis, done under the supervision of André Leroi-Gourhan, La Signification de l’art rupestre paléolithique (published in 1962),

dismissed the various, too creative theories of its predecessors, and, with them, any residual nineteenth-century prejudice or romance about the "primitive" mind. Laming-Emperaire's structuralist methodology is still in use, much facilitated by computer science. It involves compiling minutely detailed inventories and diagrams of the way that species are grouped on the cave walls; of their gender, frequency, and position; and of their relation to the signs and handprints that often appear close to them.^[2]
