Rudolf Fyodorovich Vilde (1868-c.1942) was a prolific artist for the State Porcelain Manufactory, producing dynamic designs under the influence of Chekhonin. Born in Friedrichstadt, Courland, he graduated from the Stieglitz School of Technical Drawing, St Petersburg, in 1899, followed by further study on a scholarship to France, Germany and Italy before joining the Imperial Porcelain Factory in 1905, taking charge of the artistic workshops the following year. One of the few artists to remain through the revolution, he was made head of the painting workshops, becoming director of the factory in 1930, but falling foul of Stalin’s regime in about 1936 he seems to disappear from the scene and the date of his death remains uncertain.

Vilde's original design is held by the Museum of the Imperial Porcelain Factory (State Hermitage, St Petersburg, MZ-G-102) and illustrated in 'Circling the Square, Avant-Garde Porcelain from Revolutionary Russia', Tamara Kudryavtseva, London, 2004, p.160.
