Leonid Chuguevsky (1926-2000) was an ethnic Russian sinologist and archivist born and raised in Manchuria. In 1954, after teaching at various colleges in communist China, he repatriated to the Soviet Union and worked as a researcher at the Oriental Archive of the Academy of Sciences in Saint Petersburg. His most important work was sorting, indexing and publishing the Dunhuang manuscripts from the Oriental Archive. Chuguevsky compiled the catalogue of Schilling's legacy, and published a detailed review of Schilling's mission to Kyakhta [1].
