Edmund White has been a central figure in gay fiction since the nineteen-seventies. His trio of autobiographical novels captured decades of gay experience and the glory days of pre-AIDS gay culture. Now seventy-six, White says that “gay life has changed so much and as a novelist, the aesthetic has changed.” He talks to his former student, The New Yorker’s Joshua Rothman, and reads from his new novel, “Our Young Man.” If you like what you heard, subscribe to THE NEW YORKER RADIO HOUR for free.
