The screenplay for the renowned musical The King and I was based on this title - Anna and the King of Siam, written in 1944 by Margaret Landon. ... The book took inspiration from the memoirs of a lady called Anna Leonowens, who spent several years living among the Siamese Royal Family. In the early 1860s, Anna Leonowens, a widow with two young children, was invited to Siam by King Mongkut, who wanted her to teach his children and wives the English language and introduce them to westernised customs.
