Portrait of Mademoiselle Marie Murer (Portrait de Mademoiselle Marie Murer)

Portrait of Mademoiselle Marie Murer of 1877 depicts the daughter of Eugène Murer, a pastry cook and amateur painter who was among the most loyal patrons of the Impressionist group in the 1870s. Murer regularly purchased Impressionist paintings and hosted dinners for the group at his restaurant on the Boulevard Voltaire, where he brought together Renoir, Pissarro, Sisley, Monet, and Guillaumin with the critic Théodore Duret and the dealer Père Martin. His daughter Marie-Louise — Marie Murer — was about fourteen in 1877 and appears in this portrait with the directness and personal warmth that characterized all Renoir's best figure subjects. The portrait documents not only Renoir's gift for child and adolescent portraiture but the specific social world of Impressionist patronage in the 1870s, when a network of devoted individual collectors — Murer, the Charpentiers, Caillebotte, Faure — sustained the movement financially before institutional acceptance arrived. The Barnes Foundation's acquisition of this specific patron-family portrait preserved a document of the social world that made Impressionism possible.

Renoir paints Marie in a high-key palette with warm rose and cream tones. The face shows his characteristic attentiveness to the specific physiognomy of the child — not idealized but affectionately observed. The background is loosely indicated to keep focus on the face. Brushwork is fluid and warm throughout.
