Born in Washington, D.C. in 1936 to a bookish British father and a tomboy American mother, Florence King spent her childhood living with her parents, her maternal grandmother, and her grandmother's maid.
King showed talent in French, but unable to pursue it as a major at American University, she switched to a dual major of history and English. She attended the University of Mississippi for graduate school, but did not complete her M.A. degree after discovering she could make a living as a writer.
King, who lived in Fredericksburg, Virginia at the time of her death, retired in 2002, but resumed writing a monthly column for National Review in 2006. She died on January 6, 2016 at the age of 80.
