George Bernard Shaw was an Irish playwright, critic, and polemicist who was one of the most influential playwrights in history. He is known for plays that challenged prevailing views on morality and hypocrisy such as Mrs. Warren's Profession and Pygmalion. Shaw was a brilliant human being who even at an old age felt he still had more to learn, as evidenced by his quote on his 75th birthday that he finally knew enough to become a mediocre office boy.
