Biographical Note

South Carolina plantation owner, physician, and naturalist, after whom Karl Linnaeus named the "Gardenia." Alexander Garden married Elizabeth Peronneau (d. 1805). Garden remained loyal to the Crown, although his son, Alexander Garden (1757-1829) supported the colonial cause in the American Revolution. Garden was vice-president of the British Royal Society and died in London in 1791.

John Gerar William De Brahm (geographer, climatologist, meteorologist, navigator, surveyor, and military engineer) was a Dutch Protestant who founded the colony of Bethany in Georgia. De Brahm served as an engineer in Emperor Charles VI's army before proceeding in 1751 to Georgia with 160 Protestant Salzburgers. De Brahm is noted for his work on the first comprehensive map of South Carolina and Georgia, the improvement of fortifications in Charleston and Savannah, and the construction of forts and batteries. De Brahm married Mary Drayton of Charleston on February 18, 1776. By 1791 De Brahm resided in Philadelphia.

DeBrahm's treatise "The Levelling Balance and Counter-balance; or, the Method of Observing, by the Weight and Height of Mercury" was published in 1774.
