pierre bonnard louvre bonnarding 2632237

French Post-Impressionist artist Pierre Bonnard was known for his compulsive habit of retouching his paintings long after they were considered finished, even allegedly sneaking into museums and collectors' homes with a hidden palette and brush to make adjustments. According to the article, Bonnard would enlist friends like fellow artist Édouard Vuillard to distract guards while he worked, and the poet Jane Hirschfield coined the term "bonnarding" to describe this obsessive practice. The article recounts a persistent rumor that Bonnard was once arrested in the Louvre while retouching his own work, though this is likely a myth.
