Rosemary Sutcliff was on born December 14, 1920 in East Clandon in Surrey, England. As a child she had Still's Disease, a form of juvenile arthritis. The effect of this led to many stays in hospital for painful remedial operations. She ended her formal education at fourteen, and went to Bideford Art School. She passed the City and Guilds examination and worked as a painter of miniatures. She felt cramped by the small canvas of miniature painting and turned to writing. Her first two books, The Chronicles of Robin Hood and The Queen Elizabeth Story, were published in 1950. Her other works included The Eagle of the Ninth, The Silver Branch, Sword Song, and the autobiography Blue Remembered Hills. She won the annual Carnegie Medal from the Library Association for The Lantern Bearers in 1959 and the annual Horn Book Award for Tristan and Iseult in 1971. She won inaugural Phoenix Award in 1985 for The Mark of the Horse Lord and again in 2010 for The Shining Company. In 1975, she was appointed an Officer of the Order of the British Empire for services to children's literature, and was promoted to be a Commander of the Order of the British Empire in 1992. She died on July 23, 1992.
