Elizabeth, Princess Bibesco (née Elizabeth Charlotte Lucy Asquith; 26 February 1897, London – 7 April 1945, Bucharest) was an English writer and socialite. She was the daughter of a British Prime Minister and the wife of a Romanian aristocrat. Active as a writer between 1921 and 1940, she drew on her experience in British high society in her work. A final posthumous collection of her stories, poems and aphorisms was published under the title Haven in 1951, with a preface by Elizabeth Bowen.
Elizabeth Charlotte Lucy was the first child of Herbert Henry Asquith (British Prime Minister, 1908–1916) and his second wife, Margot Tennant. As candidly recorded in her mother's 1920 autobiography, she was a precocious child of uncertain temper.
Life as the Prime Minister's daughter thrust her into the public eye at an early age and she developed a quick wit and a social presence beyond her years. At the age of 12 she asked George Bernard Shaw to write a play to be produced by her for a charity benefit. He wrote The Fascinating Foundling, which she directed with other children as actors. When she was just 14, The Times wrote that "many members of the House have made the acquaintance of Miss Asquith and in expressing their concern for her health, have referred to her charm of manner and to the interest which she has begun already to show in political matters." As a teenager, during World War I, she was given opportunities to do "good works", organising and performing in "matinees" for the servicemen. Her first known literary effort was a short duologue called "Off and On" which she performed with Nelson Keys in 1916 at the Palace Theatre. In the same year she organised a large show of portraits by John Singer Sargent at the Grafton Galleries to aid the Art Fund and a "Poets' Reading" in aid of the Star and Garter Fund. In 1918 she played small roles in two silent war movies by D.W. Griffith, "Hearts of the World" and "The Great Love".
In 1919 she married Prince Antoine Bibesco, a Romanian diplomat stationed in London, a man 22 years her senior. It was the society wedding of the year, attended by everyone from Queen Mary to George Bernard Shaw. The wedding was filmed by the newly formed British Moving Picture News organization. After the marriage, Prince and Princess Bibesco lived in Paris at the Bibesco townhouse at 45, Quai Bourbon at the tip of the Ile St Louis looking up the river toward Notre Dame cathedral. The walls of the apartment were decorated with huge canvases by Vuillard. "They weren't pictures. They were gardens into which you walked through a frame," wrote Enid Bagnold.
