Eduardo de Valfierno Eduardo de Valfierno Eduardo de Valfierno (1850–1931), who posed as a "marqués" (marquis), was an Argentine con man who allegedly masterminded the theft of the "Mona Lisa" in 1911. In 1932 journalist Karl Decker published a story in the "Saturday Evening Post" claiming Valfierno paid several men to steal the work of art from the Louvre, including museum employee Vincenzo Peruggia. On August 21, 1911 Peruggia hid the "Mona Lisa" under his coat and simply walked out the door. Before the heist took place, Valfierno allegedly commissioned French art restorer and forger Yves Chaudron to make six copies of the
Vincenzo Peruggia with banner headlines rejoicing its return and then returned to the Louvre in 1913. While the painting was famous before the theft, the notoriety it received from the newspaper headlines and the large scale police investigation helped the artwork become one of the best known in the world. Peruggia was released from jail after a short time and served in the Italian army during World War I. He later married, had one daughter, Celestina, returned to France, and continued to work as a painter decorator using his birth name Pietro Peruggia. He died on October 8, 1925 (his 44th birthday)
