Sir Walter was a strange combination of simplicity and strength. His personal appearance was strikingly odd. Once seen, he could never be forgotten. "Although forty-eight years have passed since I met him," wrote an acquaintance, "his personality is as present to me now as it was then in the flesh. His light blue waggish eye, sheltered, almost screened, by overhanging straw-colored bushy brows, his scanty, sandy-colored hair, the length of his upper lip, his towering forehead, his abrupt movements, and the mingled humor, urbanity and benevolence of his smile." His usual costume consisted of a green cutaway coat, with short skirts and brass buttons; drab trousers, vest and gaiters; a single seal and watch-key attached to a watered black ribbon dangling from his fob; a loose, soft linen collar; a black silk neckerchief; and a low-crowned, deep-brimmed hat.
