John Singer Sargent (January 12, 1856 – April 14, 1925) was an American painter, and a leading portrait painter of his era. During his career, he created roughly 900 oil paintings and more than 2,000 watercolors, as well as countless sketches and charcoal drawings. His oeuvre documents worldwide travel, from Venice to the Tyrol, Corfu, the Middle East, Montana, Maine, and Florida.
In the early 1880s Sargent regularly exhibited portraits at the Salon, and these were mostly full-length portrayals of women, such as Madame Edouard Pailleron (1880) (done en plein-air) and Madame Ramón Subercaseaux (1881). He continued to receive positive critical notice.
Sargent's best portraits reveal the individuality and personality of the sitters; his most ardent admirers think he is matched in this only by Velázquez, who was one of Sargent's great influences. The Spanish master's spell is apparent in Sargent's The Daughters of Edward Darley Boit, 1882, a haunting interior that echoes Velázquez's Las Meninas. As in many of his early portraits, Sargent confidently tries different approaches with each new challenge, here employing both unusual composition and lighting to striking effect. One of his most widely exhibited and best loved works of the 1880s was The Lady with the Rose (1882), a portrait of Charlotte Burckhardt, a close friend and possible romantic attachment.
His most controversial work, Portrait of Madame X (Madame Pierre Gautreau) (1884) is now considered one of his best works, and was the artist's personal favorite; he stated in 1915, "I suppose it is the best thing I have done." when unveiled in Paris at the 1884 Salon, it aroused such a negative reaction that it likely prompted Sargent's move to London. Sargent's self-confidence had led him to attempt another risky experiment in portraiture—but this time it unexpectedly back-fired. The painting was not commissioned by her and he pursued her for the opportunity, quite unlike most of his portrait work where clients sought him out.
