Phillipe Buache (fl. 1700-1773) Phillipe Buache (1700 - 1773) was a late 18th century French cartographer and map publisher. Buache began his cartographic career as the workshop assistant and apprentice to the important and prolific cartographer Guillaume de L'Isle. Upon De L'Isle's untimely death, Buache took over the publishing firm cementing the relationship by marrying De L'Isle's daughter. Over the years, Bauche republished many of De L'Isle's maps and charts. Buache was eventually appointed Premier Geographe du Roi, a position created-for and previously held by Guillaume de L'Isle. Buache is best known for his introduction of hachuring as a method from displaying underwater elevation on a two dimensional map surface. Despite this important innovation and his royal post, Buache's own cartographic work is known for being speculative and generally inaccurate, especially regarding the Pacific, the northwestern parts of America, and Antarctica. Today, Buache is a favorite of speculative science and alternative history buffs who point to his wildly inaccurate maps as proof that ancient civilizations once lived under the ice in Antarctica.
