Fedor (Feodor) Ruckert

Feodor Ivanovich Rückert, (1840 in Alsace — 1917 in Moscow) was a silversmith, goldsmith, and Fabergé workmaster of German origin. At just fourteen, Rückert emigrated to Russia and began working for the aristocratic Yusupov family.

In 1886, he established his own workshop at 29 Vorontsovskaya Street in Moscow. In 1887, Ruckert began working with Russian jeweller and Fabergé egg maker, Carl Fabergé. His mark Ф.Р. (F.R. in Russian Cyrillic) can be found on cloisonné enamel objects made in Moscow, which he sold both independently, as well as under Fabergé.
