Biography
Titular chamberlain to Catherine II of Russia, and a favourite of hers since his 19th year. Son of Count Peter Shuvalov (1711-1762)1 and Mavra Shepeleva (1708-1759). Married (1762) to Ekaterina Saltykova (1743-1816).
Later sources have named Shuvalov as the likely author of a great part of Catherine II's letters.
Life with Boswell
Boswell met Shuvalov in Brunswick in 1764. On August 13 of that year, he described him, in his journal, as "a little, lively man [with] a knowledge of the names of books, if not more, and much easiness of manner. He and I were very well."
