Pygmalion

Pygmalion is a play by George Bernard Shaw, named after the Greek mythological figure. It premiered at the Hofburg Theatre in Vienna on 16 October 1913 and was first presented in German on stage to the public in 1913. Its English-language premiere took place at Her Majesty's Theatre in the West End in April 1914 and starred Herbert Beerbohm Tree as phonetics professor Henry Higgins and Mrs Patrick Campbell as Cockney flower girl Eliza Doolittle.
In ancient Greek mythology, Pygmalion fell in love with one of his sculptures, which then came to life. The general idea of that myth was a popular subject for Victorian era British playwrights, including one of Shaw's influences, W. S. Gilbert, who wrote a successful play based on the story called Pygmalion and Galatea that was first presented in 1871. Shaw would also have been familiar with the musical Adonis and the burlesque version, Galatea, or Pygmalion Reversed. Shaw's play has been adapted numerous times, most notably as the 1938 film Pygmalion, the 1956 musical My Fair Lady and its 1964 film version.
Shaw mentioned that the character of Professor Henry Higgins was inspired by several British professors of phonetics: Alexander Melville Bell, Alexander J. Ellis, Tito Pagliardini, but above all, the cantankerous Henry Sweet.
