Who? Dachshund Lover Sir Hugh Seymour Walpole (March 13, 1884 - June 1, 1941) was an English novelist. The son of an English minister, he was born in Auckland in New Zealand and educated in England. He worked as a teacher before turning to writing full time. He was a prolific and versatile writer whose works came to include short stories, gothic horror novels, biographies, plays, and screeplays. Walpole was knighted in 1937.
We don't know the name of his red long-hair dachshund, but he did include some dachshund references in his writings. From The Joyful Delaneys (1938): "He worshipped his sister, owned a dachshund called Endless, to whom he confided many of his best witticisms; he found most people extraordinarily funny." From The Inquisitor (1935): "Poor Mrs. Porteous, a colourless lady with a harassed eye and short legs that gave her an odd resemblance to a dachshund, admired him now so tremendously that he became to her St. Paul and Mussolini rolled into one."
