Alessandro Longhi was a Venetian portrait painter and printmaker in etching (mostly reproductions of paintings). He is known best for his oil portraits of Venetian nobles of state. His father was the famed genre painter Pietro Longhi. He trained under his father and Giuseppe Nogari (1699–1763). Like Sebastiano Bombelli in the prior century, Alessandro Longhi is noted for his zealous full-length depictions of robes and emblems of office. His "tumultuous and unusual (etching) technique shows first-hand knowledge of Rembrandt's etchings", according to Olimpia Theodoli.
