Mr. Kris Kringle: A Christmas Tale (Illustrated) by S. Weir Mitchell

According to Wikipedia: Silas Weir Mitchell (February 15, 1829–January 4, 1914) was an American physician and writer... In 1863 he wrote a clever short story, combining physiological and psychological problems, entitled The Case of George Dedlow, in the Atlantic Monthly. Thenceforward, Mitchell, as a writer, divided his attention between professional and literary pursuits. In the former field, he produced monographs on rattlesnake poison, on intellectual hygiene, on injuries to the nerves, on neurasthenia, on nervous diseases of women, on the effects of gunshot wounds upon the nervous system, and on the relations between nurse, physician, and patient; while in the latter, he wrote juvenile stories, several volumes of respectable verse, and prose fiction of varying merit, which, however, gave him a leading place among the American authors of the close of the 19th century. His historical novels, Hugh Wynne, Free Quaker (1897), The Adventures of François (1898) and The Red City (1909), take high rank in this branch of fiction. He was also Charlotte Perkins Gilmans doctor and his use of a rest cure on her provided the idea for The Yellow Wallpaper, a short story in which the narrator is driven insane by her rest cure.
