During World War II, German soldiers mockingly referred to the Dutch as cheeseheads due to the Netherlands' extensive dairy farming industry. In the 1969 novel Papillon, the term was used to describe the unsophisticated jurors who voted to convict the main character.[2] The Dutch language term kaaskop, literally "cheese head" or "cheese cup", is considered a profane word, and is used to refer to a Dutch person as stupid or dense.[3]
Wisconsin is associated with cheese because the state historically produced more dairy products than other American states, giving it the nickname "America's Dairyland".[4] The use of the term "Cheesehead" as a derogatory word for Wisconsinites originated with Illinoisfootball and baseball fans to refer to opposing Wisconsin sports fans. The term, however, was quickly embraced by Wisconsinites and is now a point of pride.[5]
Cheesehead hat
Rose Bruno first saw a cardboard "Cheesehead" hat at a Milwaukee Brewers vs. Chicago White Sox game in Chicago in 1987 worn by fellow Milwaukeean Amerik Wojciechowski.[6][7] Ralph Bruno later made the first one out of foam while he was cutting up his mother's couch. It was made popular by centerfielder Rick Manning, who saw the hat while playing.[8][9] Bruno started a multi-million-dollar business to sell the hats as novelties. The "Cheesehead" trademark is owned by Foamation, Inc. of St. Francis, Wisconsin, which began manufacture of the wearable, foam "Cheesehead" in 1987.[10] Along with the original Cheesehead "wedge", Foamation has made other similar "cheese" apparel, including baseball caps, cowboy hats, and earrings. In 2023, Bruno sold Foamation to the Green Bay Packers, making the Cheesehead official Packers merchandise.[11][12]
The Cheesehead gained attention in 1995, when Packers fan Frank Emmert Jr. was flying on a private plane back to Wisconsin after attending a Packers game against the Cleveland Browns and the plane crashed due to ice accumulation. Emmert suffered a broken ankle and other minor injuries but was saved from further serious injury when he used his Cheesehead for protection in the crash.[13] In 2013, sports fans of Chicago replied to their rivals by wearing cheese graters.[14]
