The United States was conceived in business, founded on business, and operated as a business—all because of the entrepreneurial mind of the greatest American businessman of any generation: George Washington. Using Washington's extensive but often overlooked financial papers, Edward G. Lengel, Chief Historian of the White House Historical Association, chronicles the fascinating and inspiring story of how this self-educated man built the Mount Vernon estate into a vast, multilayered enterprise and prudently managed meager resources to win the war of independence. Lengel’s book, “First Entrepreneur,” will transform how Americans think about George Washington and how his success in commercial enterprise influenced and guided the emerging nation. Doors open at 7 p.m., and the lecture begins at 7:30 p.m. $12 per person or $10 for Society members and volunteers. Book signing to follow lecture.
