Sophie

From Peanuts Wiki

Sophie is a friend of Clara at summer camp. She first appeared in the June 18, 1968 strip. Peppermint Patty was her tent monitor. Shirly also appears in this strip.

[edit] Behind the Scenes

Schulz's maternal grandmother was Sophia Halverson. Sophie is most likely named for her as Schulz had an aunt named Clara and a cousin named Shirley. Sophia lived with him off and on during most of his childhood. She doted on her grandson and would help him practice hockey by playing goalie in the basement of their house. Schulz immortalized her early, albeit without a name, as the sports-loving grandmother of the children in his St. Paul Pioneer Press Li'l Folks newspaper strip, which pre-dated Peanuts. ("Wow, that's the third penalty they've given Grandma for unnecessary roughness.")

Sophia Halverson also is the origin of the name Miss Halverson, the teacher Linus got after Miss Othmar left to get married.
