(CNN) -- Chocolate has never tasted so cool -- February 11 is National Peppermint Pattie Day.
Back in the 1920s, a man by the name of Henry C. Kessler founded the York Cone Company in York, Pennsylvania. As the name suggests, the company initially made ice cream cones. In 1940, Kessler wanted to expand the company's repertoire, so he added a chocolate-covered peppermint candy known as the peppermint pattie.
The candy was released locally before being distributed nationwide in 1975, shortly after Peter Paul Candy Manufacturing Company acquired the York Cone Company in 1972.
In 1978, Peter Paul merged with Cadbury Schweppes. Ten years later, Hershey's purchased Peter Paul from Cadbury Schweppes.
It's often been debated whether Charles Schulz named his tomboy character after York's popular candy, but given that York Peppermint Patties didn't reach California until 1975 (nearly 10 years after Peppermint Patty debuted in the comic strip), the scenario is unlikely.
Schulz has said, however, that the character's name was inspired by a bowl of peppermint candies.
