Anna Leonowens (26 November 1831–19 January 1915) was a British travel writer, educator and social activist, known for working in Siam from 1862–1868, where she taught the wives and children of Mongkut, king of Siam. She is also known for co-founding the Nova Scotia College of Art and Design. Leonowens's experiences in Siam were fictionalised in Margaret Landon's 1944 bestselling novel Anna and the King of Siam and in various films and television miniseries based on the book, most notably Rodgers and Hammerstein's 1951 hit musical The King and I.
