After made a courtier to then-Princess Sophie of Anhalt-Zerbst in 1744, Chernyshev remained a favorite of the future Russian monarch into the 1770s. An Imperial Russian Army officer during the Seven Years' War, Chernyshev retired in 1764, and would be ultimately promoted to General Field Marshal by Catherine II. At her appointment, Chernyshev led the College of War from 1764–1774, served as her governor-general of the Pskov and Mogilev Governorates, and was the mayor of Moscow until his death. Born a Russian count in 1722, Zakhar Grigoryevich Chernyshev () was the older brother of Ivan and Andrei Chernyshev. By 1744, Chernyshev spoke Russian, French, and German. When Princess Sophie of Anhalt-Zerbst was betrothed to Peter III of Russia in 1744, Chernyshev was chosen by Empress Elizabeth of Russia as one of three nobles to join the princess' personal court as a gentleman of the chamber. In 1745, Chernyshev's mother begged Empress Elizabeth to send her son away because she feared his infatuation with the Grand Duchess Catherine Alekseievna of Russia; Chernyshev was given a diplomatic assignment. When he returned to Saint Petersburg six years later, Chernyshev began actively courting the then-grand duchess: flattering Catherine, sending love letters, and finding occasion to recreate with the royal. Chernyshev died unexpectedly on 31 August 1784 in Moscow. At the age of 13, Chernyshev joined the Imperial Russian Army in 1735, and was promoted to "kapitan" in 1741. In 1748, he was assigned to a regiment in Moscow, and in 1750, he was promoted to the ranks of "polkovnik" and general-major. As an Imperial Russian general officer, Chernyshev commanded soldiers in the Seven Years' War. In 1757, he was at the Battle of Kolín, and in 1758, he joined forces with the Austrian army. For his leadership in the 1758 Battle of Zorndorf and the 1760 occupation of Berlin—capital of the Kingdom of Prussia, Chernyshev was awarded the Order of Saint Alexander Nevsky.
