In 1964, the film My Fair Lady, starring Audrey Hepburn and Rex Harrison, won numerous Academy Awards and the hearts of audiences worldwide. The movie was based on a stage musical of the same name, which in turn was based on the play Pygmalion by George Bernard Shaw.

Shaw shared that the character of Henry Higgins was based on various British professors of phonetics, like Alexander Melville Bell and Henry Sweet. However, the true identity of Eliza Doolittle remained unknown until 2013, when English historian Wendy Moore revealed that she was based on a real woman, known as Sabrina Sidney.
