Sir Arthur Ignatius Conan Doyle (22 May 1859 – 7 July 1930) was a Scottish writer and physician, most noted for creating the fictional detective Sherlock Holmes and writing stories about him which are generally considered milestones in the field of crime fiction.
He is also known for writing the fictional adventures of a second character he invented, Professor Challenger, and for popularising the mystery of the Mary Celeste. He was a prolific writer whose other works include fantasy and science fiction stories, plays, romances, poetry, non-fiction and historical novels.
Arthur Ignatius Conan Doyle was born on 22 May 1859 at 11 Picardy Place, Edinburgh, Scotland. His father, Charles Altamont Doyle, was English, of Irish Catholic descent, and his mother, Mary (née Foley), was Irish Catholic. His parents married in 1855. In 1864 the family dispersed due to Charles's growing alcoholism and the children were temporarily housed across Edinburgh. In 1867, the family came together again and lived in squalid tenement flats at 3 Sciennes Place. Doyle's father died in 1893, in the Crichton Royal, Dumfries, after many years of psychiatric illness.
In 1885 Doyle married Louisa (sometimes called "Touie") Hawkins, the youngest daughter of J. Hawkins, of Minsterworth, Gloucestershire, and sister of one of Doyle's patients. She suffered from tuberculosis and died on 4 July 1906. The following year he married Jean Elizabeth Leckie, whom he had first met and fallen in love with in 1897. He had maintained a platonic relationship with Jean while his first wife was still alive, out of loyalty to her. Jean died in London on 27 June 1940.
Doyle fathered five children. He had two with his first wife: Mary Louise (28 January 1889 – 12 June 1976) and Arthur Alleyne Kingsley, known as Kingsley (15 November 1892 – 28 October 1918). He had an additional three with his second wife: Denis Percy Stewart (17 March 1909 – 9 March 1955), second husband of Georgian Princess Nina Mdivani; Adrian Malcolm (19 November 1910 – 3 June 1970); and Jean Lena Annette (21 December 1912 – 18 November 1997).
