In George Bernard Shaw's play "Pygmalion," Professor Henry Higgins expertly exhibits the qualities of a gentleman through his mannerisms and interactions. Primarily, his extensive knowledge and expertise in phonetics elevate him to be well-respected within society, thus exemplifying a key aspect of a gentleman's character. Moreover, despite his oftentimes harsh nature and seemingly condescending attitude, Higgins demonstrates a degree of politesse through his choice to aid Eliza in improving her speech and social standing. Furthermore, his determination to see the experiment through to its completion, withstanding societal expectations and boundaries, reflects an unwavering commitment indicative of a true gentleman. In essence, although Higgins may possess some debatable personality traits, his intellect, benevolence, and resolve demonstrate the defining qualities of a gentleman throughout "Pygmalion."
