Helene Hanff (1916-1997) was an American writer. Born in Philadelphia, Pennsylvania, she is best known as the author of the book 84 Charing Cross Road, which became the basis for a play, teleplay and film of the same name. Her career, which saw her move from writing unproduced plays to helping create some of the earliest television dramas to becoming a kind of professional New Yorker, goes far beyond the charm of that one book. She called her 1961 memoir Underfoot in Show Business, and it chronicled the struggle of an ambitious young playwright to make it in the world of New York theatre in the 1940s and 1950s. She wrote letters all her life as well as being the author of many books for children.
