Margaret Landon (September 7, 1903 – December 4, 1993) was an American writer best remembered for
Anna and the King of Siam, her best-selling 1944 novel of the life of
Anna Leonowens which eventually sold over a million copies and was translated into more than twenty languages. In 1950, Landon sold the musical play rights to
Richard Rodgers and
Oscar Hammerstein II, who created the musical
The King and I from her book. A later work,
Never Dies the Dream, appeared in 1949.
