David Henry Hwang, Tony award-winning playwright of such plays as M. Butterfly, Yellow Face, Golden Child, and Chinglish, visited Columbia to discuss his work, including Kung Fu (inspired by the life of Bruce Lee), which will premiere this spring at the Signature Theatre Company. Joining him in conversation was theater director and Columbia professor Gregory Mosher, former head of both the Lincoln Center and Goodman Theatres, and Jean Howard, George Delacorte Professor in the Humanities at Columbia and a prominent theater scholar.
