U.S.Sherry Dyson is Mathematical expert. She was known because of his husband Chris Gardner. Chris is a well known American Business man.
Gardner's relationship with Sherry was detached, in part because he decided to abandon a medical career and also due to differences in their behavior. While still living with Sherry, he began an affair with a dental student named Jackie Medina, and she became pregnant with his child only a few months into the affair.
