Heinrich Gross was a diplomat of the Empress of Russia Elizabeth Petrovna, a foreigner on the Russian service who held some of the most important diplomatic posts of her reign. As the head of Russian diplomatic missions in European countries, he was an immediate participant in the rupture of both Franco-Russian and Russo-Prussian diplomatic relations and witnessed the beginning of the Seven Years' War, while in the capital of Saxony, besieged by Prussian troops. After that H. Gross was one of the members of the collective leadership of the Russian Collegium of Foreign Affairs. So far there is only one biographic essay about him written in the 19th century. The aims of this article are threefold. Using both published foreign affairs-related documentation and diplomatic documents stored in the Archive of the Foreign Policy of the Russian Empire, it attempts to systematize the materials of the biography of this important participant in international events.

Moreover, the account of the diplomatic career of H. Gross presented in this essay aims to generate genuine interest among researchers in the personality and professional activities of one of the most brilliant Russian diplomats of the Enlightenment Era.
