Charles Schulz based Peppermint Patty on his favorite cousin, Patricia Swanson. He based Marcie, the bookish best friend who calls her "sir," on Swanson's roommate, Elise Gallaway.
Le****ns noticed long before anyone told them.
Peppermint Patty first barreled into "Peanuts" on August 22, 1966. Schulz later said he created her in response to the women's movement. He wanted a girl who broke the rules about what girls were supposed to be, and he delivered.
In a strip where nearly every girl wore a dress, Patty wore a T-shirt, shorts, and sandals. She played every sport and beat the boys at all of them. She called Charlie Brown "Chuck," bossed around her baseball team, and was raised by a single dad who gave her the sandals she refused to give up.
She also got a D-minus on just about everything, and Schulz played that for laughs. She wasn't polished, and she wasn't trying to be.
Then, on July 20, 1971, Marcie showed up. She was quiet, nearsighted, and brilliant, and from her first line in the strip, she called Patty "sir." Patty told her to knock it off. Marcie kept doing it, and eventually Patty stopped complaining. The two became inseparable for the rest of the strip's run.
For a generation of tomboys and baby d***s reading the Sunday funnies, Peppermint Patty was the first character who looked like them. She was the girl who'd rather be on the field than in a dress, who didn't fit in, and who didn't seem to care. Marcie, quietly devoted and always by her side, completed the picture.
As le***an groups began claiming Patty as one of their own, Schulz got cagey. He downplayed the fact that the character was based on his cousin, a move his biographer described as protecting Swanson's privacy. When fans asked about the pair directly, Schulz generally brushed it off. In his view, they were kids.
The jokes never stopped anyway. For decades, Patty and Marcie have been a running gag on sketch comedy and animated shows, usually with a wink about what "sir" really meant. The joke landed because everybody already got it.
Schulz died in 2000, and the strip ended with him. The characters didn't. In 2022, Apple TV+ released a Peanuts Mother's Day special built around Peppermint Patty, who doesn't have a mom. Marcie comforts her by reminding her that families come in all kinds. "Some kids even have two moms," Marcie says.
It was the first time the franchise had acknowledged same-sex parents. Conservative outlets were outraged. Le****ns who'd been reading between the panels since the Nixon administration were not surprised.
Schulz never said Patty and Marcie were in love, and nobody can say it for him. Not every icon needs her creator's permission, though. Peppermint Patty was a tough, tomboyish girl in sandals with a devoted best friend, and q***r readers recognized her immediately.
They've been calling her "sir" ever since.
