Cathy Guisewite, the creator of the "Cathy" comic strip, didn't really want the character to be named after her. People would think that "Cathy" was based on her own life, she reasoned, and ... they would be right. Or, at least, they wouldn't be wrong.
"Cathy was kind of my heart," Guisewite says. "Other stronger characters in the strip like Andrea were more my brain. But Cathy was kind of my heart, that was me."
