Although they were a unified artistic group, the Impressionists each had a specific theme they focused on. Monet loved capturing landscapes at different times of day, while Renoir painted portraits of the upper-class French decked out in their fineries. Gustave Caillebotte, who displayed his work with the Impressionists despite not being a formal member of the group, focused on capturing working-class people going about their days. Critics of his early painting, “The Floor Scrapers,” called it crude, but no other Impressionist was able to create characters on canvas the way Caillebotte did. Unfortunately, his paintings made it into few public collections before his death, and his work wasn’t celebrated until decades later. Now, the National Gallery of Art has gathered many of his paintings from collections around the world to tell the full story of his career through self-portraits and still lifes, as well as his iconic “Paris Street, Rainy Day.” The exhibition is on view Mondays through Saturdays 10 a.m. to 5 p.m. and Sundays 11 a.m. to 6 p.m. at the National Gallery of Art, 6th Street and Constitution Avenue NW.
