Who is General Scott from Personal Memoirs of U.S. Grant and what is their importance?

Grant first met him when General Scott visited cadets at West Point. General Scott was careful about appearances and tended to have plans written and ready to be distributed when faced with any military situation. Scott was very interested in how his actions would appear to others and let his officers know when he planned to travel among the men so that the officers could ensure that everything and everyone was ready to greet Scott.
