George Washington (February 22, 1732 - December 14, 1799) was an American statesman and soldier who served as the first President of the United States from 1789 to 1797 and was one of the Founding Fathers of the United States. He served as Commander-in-Chief of the Continental Army during the American Revolutionary War, and later presided over the 1787 convention that drafted the United States Constitution. As a driving force behind the nation's establishment he came to be known as the "father of the country," both during his lifetime and to this day. Washington was born into the provincial gentry of Colonial Virginia to a family of wealthy planters who owned tobacco plantations and slaves, which he inherited.
Washington's introduction to surveying began at an early age through school exercises that taught him the basics of the profession, followed by practical experience in the field. His first experiences at surveying occurred in the territory surrounding Mount Vernon. His first opportunity as a surveyor occurred in 1748 when he was invited to join a survey party organized by his neighbor and friend George Fairfax of Belvoir. Fairfax organized a professional surveying party to lay out large tracts of land along the border of western Virginia, where Washington gained invaluable experience in the field. Washington began his professional career in 1749 at the age of 17, when he was appointed county surveyor of Culpeper County, Virginia. He subsequently received a commission and surveyor's license from the College of William & Mary. He completed his first survey in less than two days, plotting a 400-acre parcel of land. He was subsequently able to purchase land in the Shenandoah Valley, the first of his many land acquisitions in western Virginia. For the next four years, Washington worked surveying land in Western Virginia for the Ohio Company, a land investment company funded by Virginia investors. He came to the notice of the new lieutenant governor of Virginia Robert Dinwiddie, thanks to Lawrence's position as commander of the Virginia militia. In October 1750, Washington resigned his position as an official surveyor, though he continued to survey professionally for two more years before receiving a military appointment as adjutant for southern Virginia. By 1752, Washington completed close to 200 surveys on numerous properties totaling more than 60,000 acres. He continued to survey at different times throughout his life and as late as 1799.
