a Russian scientist, military engineer, inventor and sculptor. He was a personal craftsman of Peter I of Russia, and later a member of the Russian Academy of Science. In 1718 Nartov invented what might have been the first lathe with a mechanical cutting tool-supporting carriage and a set of gears (also known as a compound rest or slide rest). Among other inventions of Nartov are such things as a unique fast-fire battery on a rotating disc, a screw mechanism for changing the artillery fire angle, a gauge-boring lathe for cannon-making and an early telescopic sight.
