A Map of South Carolina
John Wilson was South Carolina’s State Civil and Military Engineer, and the creation of an accurate state map reflecting all the new internal improvements, was one of his responsibilities. The idea for this map was first proposed to the South Carolina Legislature in December of 1815 by Professor George Blackburn. Nineteen surveyors worked over a period of five years to create this map. Henry S. Tanner of Philadelphia, one of the finest cartographic engravers in America was hired to engrave and print the map. Tanner referred to this map as “one of our best and most scientific maps….”.
Constructed from local manuscript survey and compiled for use by state officials, it remained the foundation map for South Carolina until the Civil War.
