Philipp Hackert, a German artist, born at Prenzlau, Prussia, Sept. 15, 1737, died near Florence, April 28, 1807. He studied painting with his father, and afterward at Berlin, and went to Paris in 17G5, and to Italy in 1768. In Rome the empress Catharine of Russia ordered of him two pictures to represent the naval battle of Tehesme, July 5, 1770, and the burning of the Turkish fleet. In order that he might understand the appearance of the explosion of a ship, Count Orloff blew up one of his frigates before him. After the task was finished the empress ordered six pictures of the victories of the Russians in the Mediterranean. He resided for some time in Naples, but was compelled by the revolution of 1799 to go to Florence; and he purchased a villa near that city, in which he resided until his death. His contemporary reputation was beyond his merits. He engraved many of his own paintings, and wrote Sull uso della vernice nella pittura (1788), and Theoretisch-praktische Anleitung zum Landschaftszckhnen (1803). Goethe wrote a biographical sketch of Hackert (1811).
