The collection of early Modern masterpieces amassed by Sergei Shchukin—the wealthy tsarist-era businessman and arts patron—will be reunited in an exhibition at the Fondation Louis Vuitton in Paris this autumn. The works, including examples by Matisse and Picasso, were split during the Soviet regime and are now housed in the State Hermitage Museum in St Petersburg and the State Pushkin Museum of Fine Arts in Moscow.
