The exhibition is dedicated to art historian Andrei Tolstoy and reveals the scale of his scientific legacy. The focus is on books, research, and archival materials that have influenced the study of the art of the Russian diaspora. The project addresses the memory of Andrei Vladimirovich Tolstoy - a researcher whose works have largely defined the modern understanding of the art of Russian emigration in the 20th century. His scientific work united different cultural contexts, creating a lively dialogue between the domestic artistic tradition and the Western world. The exhibition features photographs capturing the art historian at various times, as well as publications that became important milestones in his professional journey. Among them are books and articles dedicated to the "Paris School," masters of the Russian diaspora, and the complex processes of artistic exchange between Russia and Europe. These publications remain a foundation for researchers and students. Special attention is given to the memorial fund stored in the museum's library. It contains over seven hundred books reflecting the breadth of the author's interests and the scale of his scientific activity. Visitors can see catalogs, albums, collections, and conference materials related to his name and works. Ideas on where to go in Moscow are gathered on our website.
