Tomás López de Vargas Machuca (1730-1802) was a Spanish cartographer active in the later part of the 18th century. Vargas was born in Toledo and studied mathematics, grammar, and rhetoric at the Colegio Imperial in Madrid. In 1752, with the patronage of the Marquis de la Ensenada, he relocated to Paris where he studied cartography under the legendary French mapmaker Jean Baptiste Bourguignon d'Anville (1697 – 1782). On his return to Spain, King Carolos III, appointed him Geógrafo de los Dominios de Su Magestad and gave him charge over the newly created Gabinete de Geografía. In this position, he dedicated the remainder of his life to a detailed mapping of Spain, producing numerous important regional maps. He was a member of the Real Academia de San Fernando, the Real Sociedad Bascongada de Amigos del País and the Academia de Bellas Letras de Sevilla. López was succeeded by his two sons, also cartographers, who published several atlases based upon his work.
