After the war, Gen. Lee tended to his sick wife with total devotion until her death. After her death, her mother became ill, and he took care of his mother-in-law with that same devotion until her death. Name another important man in our history who has done that. He was a singular man among men.
He certainly was a singular man, considering his wife died in 1873. So I can't name another man, important or unimportant, who was caring for his wife three years after he died.
And while we're on the subject, his mother-in-law died in 1853.
Dude, given the general condition of life in the 18th. century and what passed for health care what he did was not remarkable, it was the norm.
