Algernon Henry Blackwood, CBE (14 March 1869 – 10 December 1951) was an English short story writer and novelist, one of the most prolific writers of ghost stories in the history of the genre. He was also a journalist and a broadcasting narrator. S. T. Joshi has stated that "his work is more consistently meritorious than any weird writer's except Dunsany's" and that his short story collection Incredible Adventures (1914) "may be the premier weird collection of this or any other century."
Throughout his adult life, he was an occasional essayist for various periodicals. In his late thirties, he moved back to England and started to write stories of the supernatural. He was very successful, writing at least ten original collections of short stories and eventually appearing on both radio and television to tell them. He also wrote fourteen novels, several children's books, and a number of plays, most of which were produced but not published. He was an avid lover of nature and the outdoors, and many of his stories reflect this. To satisfy his interest in the supernatural, he joined the Ghost Club. He never married; according to his friends he was a loner but also cheerful company.
Blackwood died after several strokes. Officially his death on December 10, 1951 was of cerebral thrombosis with arteriosclerosis as contributory. He was cremated at Golders Green crematorium. A few weeks later his nephew took his ashes to Saanenmoser and scattered them over the mountains that he had loved for over forty years.
