#OTD in 1911.
Leonardo da Vinci's Mona Lisa was stolen from the Louvre by museum employee Vincenzo Peruggia and was not recovered until two years later.
The theft and subsequent recovery in 1913 led to the publication of many cultural depictions such as the 1915 opera Mona Lisa, two early 1930s films (The Theft of the Mona Lisa and Arsène Lupin) and the song "Mona Lisa" recorded by Nat King Cole—one of the most successful songs of the 1950s.
