Who among the following was a notable salonniere?

A notable salonniere is someone who hosts social gatherings or salons, often involving intellectual discussion, art, and culture. Elisabeth Vigee-Lebrun, a prominent French painter of the late 18th century, played a significant role in the art world not only through her own work but also through her influence as a salonniere. Her salons provided a space for artists, thinkers, and influential figures of her time to convene, discuss their ideas, and promote the arts.

In contrast, the others on the list were not known for hosting salons. Johann Vermeer was renowned for his paintings characterized by their use of light and domestic scenes, but he did not engage in hosting salons. Michelangelo and Leonardo da Vinci were key figures in the High Renaissance known primarily for their contributions to sculpture, painting, and architecture rather than for any social gatherings or salon culture. Therefore, Vigee-Lebrun's prominent role in salon culture makes her the correct choice.
