Als, a theater critic for the New Yorker, won a Pulitzer Prize in criticism. His work often furthers discussions on the intersections of theater, race, identity, sexuality and class in the United States. This can be seen in his January 2016 review of Broadway musical DreamGirls, which was one of his 10 pieces that were reviewed before awarding Als the award.
