Sir Arthur Ignatius Conan Doyle was born the third of ten siblings on 22 May 1859 in Edinburgh, Scotland. His father, Charles Altamont Doyle, a talented illustrator, was born in England of Irish descent, and his mother, born Mary Foley, was Irish. They were married in 1855. Although he is now referred to as "Conan Doyle", the origin of this compound surname (if that is how he meant it to be understood) is uncertain. His baptism record in the registry of St Mary's Cathedral in Edinburgh gives 'Arthur Ignatius Conan' as his Christian name, and simply 'Doyle' as his surname. It also names Michael Conan as his godfather. At the age of nine Conan Doyle was sent to the Roman Catholic Jesuit preparatory school, Hodder Place, Stonyhurst. He then went on to Stonyhurst College, leaving in 1875. From 1876 to 1881 he studied medicine at the University of Edinburgh. This required that he provide periodic medical assistance in the towns of Aston (now a district of Birmingham) and Sheffield. While studying, Conan Doyle began writing short stories. His first published story appeared in "Chambers' Edinburgh Journal" before he was 20. Following his graduation, he was employed as a ship's doctor on the SS Mayumba during a voyage to the West African coast. He completed his doctorate on the subject of tabes dorsalis in 1885. In 1885 Conan Doyle married Louisa (or Louise) Hawkins, known as "Touie". 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. Due to his sense of loyalty he had maintained a purely platonic relationship with Jean while his first wife was alive. Jean died in London on 27 June 1940. Conan Doyle fathered five children. 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). With his second wife he had three children—Denis Percy Stewart (17 March 1909 – 9 March 1955), second husband in 1936 of Georgian Princess Nina Mdivani (circa 1910 – 19 February 1987; former sister-in-law of Barbara Hutton); Adrian Malcolm (19 November 1910–3 June 1970) and Jean Lena Annette (21 December 1912–18 November 1997). Conan Doyle was found clutching his chest in the hall of Windlesham, his house in Crowborough, East Sussex, on 7 July 1930. He had died of a heart attack at age 71. His last words were directed toward his wife: "You are wonderful." The epitaph on his gravestone in the churchyard at Minstead in the New Forest, Hampshire, reads: STEEL TRUE BLADE STRAIGHT ARTHUR CONAN DOYLE KNIGHT PATRIOT, PHYSICIAN & MAN OF LETTERS Conan Doyle's house, Undershaw, located in Hindhead, south of London, where he had lived for a decade, had been a hotel and restaurant between 1924 and 2004. It now stands empty while conservationists and Conan Doyle fans fight to preserve it. A statue honours Conan Doyle at Crowborough Cross in Crowborough, where Conan Doyle lived for 23 years. There is also a statue of Sherlock Holmes in Picardy Place, Edinburgh, close to the house where Conan Doyle was born. Series: * Sherlock Holmes

É o autor da letra do Hino da Proclamação da República. Na imprensa, escreveu também sob os pseudônimos Armando Quevedo, Atásius Noll, J. dos Santos, Max, Rifiúfio Singapura. Membro da Academia das Ciências de Lisboa. A 7 de Junho de 1922 foi feito Comendador da Ordem Militar de Cristo de Portugal e a 19 de Abril de 1940 foi feito Comendador da Ordem Militar de Sant'Iago da Espada de Portugal. Durante boa parte de sua vida foi um ateu convicto, porém converteu ao catolicismo. Em 1924, Medeiros e Albuquerque publicou um interessante livro intitulado "Tests". Com o subtítulo de "Introdução ao estudo dos meios científicos de julgar a inteligência e a aplicação dos alunos", a pequena obra, pretendia trazer para o cenário brasileiro, principalmente para o ensino de psicologia nas escolas normais, o movimento que crescia nos Estados Unidos com relação ao uso de testes psicológicos. O livro de Medeiros e Albuquerque, muito bem referendado bibliograficamente dentro de sua época, introduz o leitor nos testes de inteligência (individuais e coletivos) e discute a utilização do emprego de testes como forma de avaliação aprendizagem. O próprio autor sugere que seu livro seja a primeira publicação brasileira sobre assunto.

Richard Horatio Edgar Wallace (1875-1932) was a prolific British crime writer, journalist and playwright, who wrote 175 novels, 24 plays, and countless articles in newspapers and journals. Over 160 films have been made of his novels, more than any other author. In the 1920s, one of Wallace's publishers claimed that a quarter of all books read in England were written by him. He is most famous today as the co-creator of "King Kong", writing the early screenplay and story for the movie, as well as a short story "King Kong" (1933) credited to him and Draycott Dell. He was known for the J. G. Reeder detective stories, The Four Just Men, the Ringer, and for creating the Green Archer character during his lifetime.
