I seem to recall that George was also rather tall among his contemporaries. If you add hair, a spiffy outfit (especially a military uniform), along with his intellect, bravery and passion for doing the right thing for the right reasons, I bet he was quite the figure of Revolutionary Manly Sexiness. No wonder Martha was so smitten.
Washington was 6' 2" tall, extraordinary for his time and place. He took care to present an elegant image, with well tailored attire, as he believed that a leader should look and act the part. His personal demeanor was described both as unasssuming and yet magisterial--a man of unprecedented charisma in the New World, and according to contemporaries, he was everything his later hagiographers said of him.
