Count Jerzy Detloff Flemming (1699–1771) was a general of artillery and a Great Treasurer of Lithuania and the Pomeranian Voivodeship. He was the son of Count Felix Friedrich von Flemming (1661–1739), a Prussian Privy Councillor. The Count's family were well-known magnates with a long tradition of military service. Flemming was married to Princess Konstancja Czartoryska, the daughter of Prince Michal Fryderyk Czartoryski and Eleonora Monika Waldstein. After the death of his first wife, the Count married her sister, Princess Antonina Czartoryska. The waist-length image of a man turned in three quarters, looking at the viewer, is a prominent example of Antoine Pesne's portrait painting. The Count is wearing armour with a blue order ribbon. The man's face and gleaming armour surface are rendered realistically, in detail, emphasising his status and rank.
