During the Revolution, John (Jean) Christian Senf, a native of Sweden, served as an engineer for South Carolina and Virginia. In describing him to Jefferson, Gen. Horatio Gates called Senf “the best Draughtsman I know, and an Excellent Engineer” (Gates to Jefferson, 24 Sept. 1780, JEFFERSON [1] description begins Julian P. Boyd et al., eds. The Papers of Thomas Jefferson. 40 vols. to date. Princeton, N.J., 1950—. description ends , 3:662). After the war Senf returned to Europe but came back to America in 1785. It was during this year that legislation was passed in South Carolina authorizing construction of the Santee canal to connect the Santee and Cooper rivers. Senf became the chief engineer for that project. In 1789 Senf discussed with GW the possibility of conducting a survey of inland navigation from New York to East Florida (GW to Senf, 12 Oct. 1789, DLC:GW).
