Elizabeth Jane Gardner was an American academic and salon painter, who was born in Exeter, New Hampshire. She was an American expatriate who died in Paris where she had lived most of her life. She studied in Paris under the figurative painter Hugues Merle (1823–1881), the well-known salon painter Jules Joseph Lefebvre (1836–1911), and finally under William-Adolphe Bouguereau (1825–1905). After Bouguereau's wife died, Gardner became his paramour and after the death of his mother, who bitterly opposed the union, she married him in 1896.

She adopted his subjects, compositions, and even his smooth facture, channeling his style so successfully that some of her work might be mistaken for his. In fact, she was quoted as saying, "I know I am censured for not more boldly asserting my individuality, but I would rather be known as the best imitator of Bouguereau than be nobody!"

Gardner's best known work may be The Shepherd David Triumphant (1895), which shows the young shepherd with the lamb he has rescued. Among her other works were Cinderella, Cornelia and Her Jewels, Corinne, Fortune Teller, Maud Muller, Daphne and Chloe, Ruth and Naomi, The Farmer's Daughter, The Breton Wedding, and some portraits.
