Baroness Emma Orczy (full name: Emma Magdalena Rozália Mária Jozefa Borbála Orczy de Orci) (; 23 September 1865 – 12 November 1947), usually known as Baroness Orczy (the name under which she was published) or to her family and friends as Emmuska Orczy, 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 French aristocrats from "Madame Guillotine" during the French Revolution, establishing the "hero with a secret identity" in 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. She established the Women of England's Active Service League during World War I with the intention of empowering women to convince men to enlist in the military.
