1911: The Mona Lisa Stolen from the Louvre by a Museum Employee
In the early hours of 21 August 1911, Vincenzo Peruggia, an Italian handyman who had worked at the Louvre, hid inside the museum overnight, lifted Leonardo da Vinci’s Mona Lisa from the wall, concealed it under his coat, and walked out. The theft went unnoticed for nearly 24 hours. The empty hooks on the wall were initially assumed to mean the painting had been taken for photography.
Peruggia kept the masterpiece hidden in his Paris apartment for over two years before attempting to sell it to an art dealer in Florence. He was arrested in December 1913, and the painting was recovered intact. Peruggia claimed he had acted out of Italian patriotism, believing the work had been stolen by Napoleon and deserved to be returned to Italy. He served just seven months in prison.
