Anna Harriette Leonowens (6 November 1831 - 19 January 1915) born Anna Harriet Emma Edwards, was an Anglo-Indian or Indian-born British travel writer, educator, and social activist. Her experiences in Siam (Thailand) were fictionalised in Margaret Landon's 1944 best-selling novel Anna and the King of Siam, as well as films and television series based on the book, most notably Rodgers and Hammerstein's 1951 hit musical The King and I.
