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 to Italy with it. He kept it in his apartment in Florence, Italy but grew impatient, and was finally caught when he contacted Alfredo Geri, the owner of an art gallery in Florence. Geri's story conflicts with Peruggia's, but it was clear that Peruggia expected a reward for returning the painting to what he regarded as its "homeland". Geri called in Giovanni Poggi, director of the Uffizi Gallery, who authenticated the painting. Poggi and Geri, after taking the painting for "safekeeping", informed the police, who arrested Peruggia at his hotel. After its recovery, the painting was exhibited all over Italy
