Baroness Emma Magdolna Rozália Mária Jozefa Borbála "Emmuska" Orczy de Orci (23 September 1865 – 12 November 1947) was a Hungarian-born British novelist and playwright. She is best known for her series of novels featuring the Scarlet Pimpernel, the alter ego of Sir Percy Blakeney, a wealthy English fop who turns into a quick-thinking escape artist in order to save ill-fated French royalty from "Madame Guillotine" during the French revolution, establishing the "hero with a secret identity" into popular culture. Opening in London's West End on 5 January 1905, The Scarlet Pimpernel became a favourite of British audiences. Some of Orczy's paintings were exhibited at the Royal Academy in London. During World War I, she formed the Women of England's Active Service League, an unofficial organization aimed at encouraging women to persuade men to volunteer for active service in the armed forces. Emmuska Orczy was born in Tarnaörs, Heves County, Hungary, and was the daughter of composer Baron Félix Orczy de Orci (1835–1892) and Countess Emma Wass de Szentegyed et Cege (1839–1892). Her grandfather, Baron László Orczy (1787–1880) was a royal councillor, and knight of the Sicilian order of Saint George, her grandmother was the Baroness Magdolna Müller (1811–1879). Her maternal grandparents were the Count Sámuel Wass de Szentegyed et Cege (1815–1879), member of the Hungarian parliament, and Rozália Eperjessy de Károlyfejérvár (1814–1884). Orczy's novels were racy, mannered melodramas and she favoured historical fiction. Critic Mary Cadogan states, "Orczy's books are highly wrought and intensely atmospheric". Less
