This thesis examines the portraiture of Elisabeth Vigée-Lebrun and Adélaide Labille-Guiard within the context of their time. Analysis of specific portraits in American collections is provided, along with an examination of their careers: early education, Academic Royale membership, Salon exhibitions, and the French Revolution. Discussion includes the artists' opposing stylistic heritages, as well as the influences of their patronage, the French art academy and art criticism. This study finds that Salon critics compared their paintings, but not with the intention of creating a bitter personal and professional rivalry between them as presumed by some twentieth-century art historians. This thesis concludes those critics simply addressed their opposing artistic styles and that no such rivalry existed.
