Which Peanuts character is a bookworm who wears glasses?

The Peanuts character who is a bookworm and wears glasses is Marcie.

Marcie is portrayed as an intelligent, studious girl and is one of the strongest students in the Peanuts cast. Her round glasses and short bobbed hair make her immediately recognizable. Her academic ability often contrasts with her best friend Peppermint Patty, who is athletic but famously struggles with schoolwork.

Marcie first appeared at a summer camp with Peppermint Patty in July 1971 and was named in the comic strip later that year. From the beginning, she called Peppermint Patty “Sir,” a running gag that reflects Marcie’s formal, understated manner. She calls Charlie Brown “Charles,” another detail associated with her character.

Although Marcie is book-smart, she is not defined only by studying. She is also musically talented, speaks French in some stories, and is often poor at sports. Her glasses usually have opaque lenses, concealing her eyes; a rare 1980 strip showed her without them.

Readers sometimes confuse Marcie with Lucy or Sally because all three are prominent Peanuts girls, but the glasses, academic personality, and close friendship with Peppermint Patty identify Marcie.
