william gerard de brahm (1718 - 1799)
Johann Wilhelm Gerhard von Brahm, also known as John William Gerard de Brahm, was a German cartographer, military engineer, and surveyor who worked for Great Britain to develop the lands of the New World.
His father was court musician to the Elector of Trier and gave his son an excellent early education. After a successful career as a military engineer in the Bavarian army, de Brahm traveled to Georgia in 1751 at the head of a group of German emigrants. There he displayed his talents as a surveyor and engineer, worked as a cartographer, and was commissioned by South Carolina Governor James Glen to design and build a system of fortifications for Charleston.
In 1755 de Brahm was appointed inspector general of lands for South Carolina and soon for the entire New World. He settled in St. Augustine, where he spent the next six years researching and preparing maps. His major works, "Map of South Carolina" and "Map of South Carolina and Part of Georgia," provide detailed topography and even describe underwater features. And his "Report of a General Survey of the Southern District of North America" records every detail from tide times to tips on tilling the soil. De Brahm's book The Atlantic Pilot, an instruction manual for sailing in Florida, was published in London and included the first published map of the Gulf Stream.
