The relationship between Alexander and Elizabeth was best summed up by the Countess of Choisseul-Gouffier in her memoirs:
"What a difference would it have made in the happiness of both, if they had been able to understand each other! They seemed to have been made the one for the other; the same goodness, the same gentleness and intellectual power. Yet there seemed to have been one point on which their hearts could not meet. Why is it that death alone has reunited such perfect souls?"
