Ivan Chernyshyov

He started his career serving under his more illustrious brother Zakhar Chernyshyov at the Russian missions in Copenhagen (1741) and Berlin (1742–45).

All three Chernyshov brothers backed Catherine in the coup that placed her on the Russian throne in 1762, after the assassination of her husband, Peter III.

[5] Being on friendly terms with Nikita Panin, the tutor and closest adviser to the future Emperor Paul, he was promoted to the rank of Navy Field Marshal upon the latter's ascension to the throne.

[8] Zakhar’s sister, Alexandra ("Alexandrine") Chernysheva, was married to the author of the Decembrist constitution, Nikita Muravyov.

[9][10] Chernyshov's niece, Natalya Petrovna Galitzine, better known at the Russian court as "Princesse Moustache", was romanticized by Pushkin under the name of The Queen of Spades in his eponymous story from 1834.
