Marie Adelaide Lowndes née Belloc (1868 - 1947). Mrs. Belloc Lowndes, was an English novelist, born in Marylebone, London, the only daughter of French barrister Louis Belloc and Bessie Parkes, and sister of Hilaire Belloc. Her paternal grandfather was the French painter Jean-Hilaire Belloc and her maternal great-grandfather was Joseph Priestley. In 1896 she married Frederic Sawrey Lowndes. Mrs. Lowndes established her reputation as a teller of stories combining exciting incident with psychological interest. Her first novel The Heart of Penelope was published in 1904. From then on novels, reminiscences and plays came from her quill at the rate of one per year until 1946. In the novel, I, too, Have Lived in Arcadia, published in 1942, Mrs. Belloc Lowndes told the story of her mother's life, compiled largely from old family letters, and of her own early life in France. Her most famous novel is The Lodger, published in 1913. Based on the Jack the Ripper murders, it is about a London family who suspects that their upstairs lodger is a mysterious killer known as "The Avenger." The novel was the basis for four movie adaptions. The first was the silent film version directed by Alfred Hitchcock in 1927, it was followed by several remakes. The film was remade by Maurice Elvey in 1932, John Brahm in 1944, as Man in the Attic in 1953, and once again by David Ondaatje in 2009. She died November 14, 1947 at the home of her elder daughter, Countess Iddesleigh (wife of the third Earl[1]), in Eversley Cross, Hampshire. She was interred in France, in La Celle-Saint-Cloud near Paris & Versailles, where she spent her youth.
