Jean Maritz (1680–1743), also Johan Maritz, was a Swiss inventor, born in Burgdorf, Canton of Bern, who moved to France, becoming "Commissaire des Fontes" at Strasbourg (Commissioner of the King's Foundry), and invented the vertical drilling machine, as well as the horizontal drilling machine for cannons in the 18th century. His inventions revolutionized cannon-making and became a key component of the de Vallière system and contributed to the development of the later Gribeauval system.
