Robert, age 50-60. In his 20s Robert made historic breakthroughs in the field of mathematics. He became a professor of mathematics. He is the father of Catherine and Claire, and Hal was a former student. Robert suffers from mental illness that compromises his ability to do his work and to function normally.

Claire, age 29, is a professional in New York. She is buttoned up and more middle class than her academic father and sister. She is focused on her upcoming marriage. Mostly she has ignored her father and his illness. Her concern for her sister is real and she wants to do the right thing.

Hal, age 28, is a former student of Robert and he is passionately interested in the work Robert might have achieved during his illness. His romantic interest in Catherine heightens the drama of the play. He is a math geek, a musician, animated and a truly good person. The circumstances of the drama affect him deeply.
