Isabella Stewart Gardner Museum theft

In the early morning hours of March 18, 1990, 13 works of art were stolen from the Isabella Stewart Gardner Museum in Boston. Guards admitted two men posing as police officers responding to a disturbance call, and the thieves bound the guards and looted the museum over the next hour. The case is unsolved; no arrests have been made, and no works have been recovered. The stolen works have been valued at hundreds of millions of dollars by the FBI and art dealers. The museum offers a $10 million reward for information leading to the art's recovery, the largest bounty ever offered by a private institution.

The stolen works were originally procured by art collector Isabella Stewart Gardner (1840–1924) and were intended for permanent display at the museum with the rest of her collection. Among them was The Concert, one of only 34 known paintings by Johannes Vermeer and thought to be the most valuable unrecovered painting in the world. Also missing is The Storm on the Sea of Galilee, Rembrandt's only seascape. Other paintings and sketches by Rembrandt, Edgar Degas, Édouard Manet and Govert Flinck were stolen, along with a relatively valueless eagle finial and Chinese gu. Experts were puzzled by the choice of artwork, as more valuable works were left untouched. As the collection and its layout are intended to be permanent, empty frames remain hanging both in homage to the missing works and as placeholders for their return.

The FBI believes that the robbery was planned by a criminal organization. The case lacks strong physical evidence, and the FBI has largely depended on interrogations, undercover informants and sting operations to collect information. It has focused primarily on the Boston Mafia, which was in the midst of an internal gang war during the period. One theory holds that gangster Bobby Donati organized the heist to negotiate for his caporegime's release from prison; Donati was murdered one year after the robbery. Other accounts suggest that the paintings were stolen by a gang in Boston's Dorchester neighborhood, although these suspects deny involvement despite the fact that a sting operation resulted in several prison sentences. All have denied any knowledge or have provided leads that proved fruitless, despite the offer of reward money and reduced or canceled prison sentences if they had disclosed information leading to recovery of the artworks.
