Higgins is an extremely interesting character and the life of the play. Although the play's obvious concern is the metamorphosis of a common flower girl into a duchess, the development of Higgins' character is also important. The play isn't only Eliza's story.

These quirks and oddities of his character contribute to the laughs in the play and place Higgins in the tradition of the comic hero.
It is obvious that simply as a professor of phonetics Higgins would not have been very...
