Who is this person?

[RJNorton]

What person described Abraham Lincoln as follows?

"He was tall and thin, with enormously long loose arms and big hands, and long legs ending with feet such as I never saw before; one of his shoes might have served Commodore Nutt as a boat. The manner in which he dressed made him appear even taller and thinner than he was, for the clothes he wore seemed to be transmitted to him by some still taller elder brother. In summer, when he wore a suit made of some light black stuff, he looked like a German village schoolmaster. He had very large ears standing off a little, and when he was in a good humour I always expected him to flap with them like a good-natured elephant."
