George Washington (February 22, 1732 – December 14, 1799) was an American political leader, military general, statesman, and founding father who served as the first president of the United States from 1789 to 1797. Previously, he led Patriot forces to victory in the nation's War for Independence. He presided at the Constitutional Convention of 1787, which established the U.S. Constitution. Washington did not have the formal education his elder brothers received at Appleby Grammar School in England, but he did learn mathematics, trigonometry, and land surveying. He was a talented draftsman and map-maker. By early adulthood he was writing with 'considerable force' and 'precision', however his writing displayed little wit or humor. In pursuit of admiration, status, and power, he tended to attribute his shortcomings and failures to someone else's ineffectuality.
