Generally speaking, when I see just "Washington" in reference to a person, I assume this refers to George Washington, the first president of the United States. He was born February 22nd, 1732 and died December 14th, 1799. He was 67 years old when he died.
In George Washington's 67 years of life, he accomplished many things. He fought in both the French and Indian War and the American Revolutionary War, the latter of which he served as Commander-in-Chief of the Continental Army (precursor to the present day United States Army). He was later elected the first United States president by unanimous vote of the first electoral college, and he is the only president to not have belonged to a political party. He stepped down after two terms, which expired in March 1797, and died two years later of a combination of breathing difficulties and excessive blood loss from a medical procedure popular at the time, bloodletting.
