Louis Béroud (January 17, 1852, Lyon-October 9, 1930, Paris) was a French painter of the late 19th, early 20th century.
Some of his paintings are visible at the Musée Carnavalet and The Louvre in Paris.
On August 22, 1911, Béroud came to The Louvre to sketch his painting Mona Lisa au Louvre but where the famous La Joconde, by Leonardo da Vinci, should have stood, he found four iron pegs.
Béroud contacted the section head of the guards, who thought the painting was being photographed for marketing purposes.
