Kramer was born June 25, 1935. The Normal Heart chronicled the early days of the AIDS epidemic, notably the resistance by the political establishment to recognize it and do something about it. In the play, Kramer also portrayed himself as pushy and obnoxious, including in his relations with leaders of gay political organizations, whom he felt were too timid in campaigning for help. The Normal Heart originated in 1985 at the Public Theater Off-Broadway. It was revived on Broadway in 2011, winning the Tony for Best Revival. That led to an emmy-winning 2014 film adaptation that also debuted at the Sundance Film Festival also was shown on HBO.
